blockchain – Why have there not been any “Bitcoin hardfork” as in “split coins” for years and years?

A few years ago, there was a wonderful short period where Bitcoin was “hardforked” multiple times to create these “sillycoins” where you got as many sillycoins as you had Bitcoin at the time of the split. Then you could use those to buy more Bitcoin. That’s what I did with all of mine. In total, I made more than one whole shiny Bitcoin, impossible for me to afford otherwise.

Ever since, I’ve searched and hoped for something like that to happen again, but it has not. Or, if it has, I managed to miss it.

But why is this? Did this only work “once” for some reason? Why aren’t there regular such “split coins” made for the sole purpose of gaining more Bitcoin? It was quite a nightmare to try to semi-trust their weird fullnode clients inside a VM and syncing the massive blockchains which took over a week each. So it’s not like it means that you snap your fingers to give every Bitcoin owner more BTC. It took a lot of work and patience, and most people probably had no idea about this. I only knew out of sheer dumb luck. I might as well have missed that whole “gold rush”.

Since I have so extremely little fiat money, I cannot buy more Bitcoin. I struggle to find some way to increase my meager Bitcoin collection. Mining is of course not possible and hasn’t been for many years.

bitcoin core – To test if my wallet.dat encryption password is correct, MUST I spend coins?

When a Bitcoin Core wallet is encrypted, you (apparently) have to enter the decryption passphrase only when trying to spend coins. You still get to “use” the wallet as in seeing all the transactions and labels.

I’m worried that my saved passphrase (partially on the computer/paper and in my head) is not correct. But to test this, I would have to spend coins… or do I?

I suspect that you’ll say: “Use the change passphrase feature!”

But that would just put me again in the same situation. Of course, I had to repeat the passphrase (two times in total) to enter it in the first place, and this would be done again. So I’d again be paranoid that my keyboard has a faulty key or something like that.

Is there some way to “test unlock” a wallet without actually spending any money?

bitcoin core – “At first, anyone could spend anyone’s coins”?

I’ve been watching this Bitcoin video:

At the linked-to timestamp, he claims that:

Due to bugs, at first, anyone could spend anyone’s coins!

I’m not saying that I think he’s lying, but was Bitcoin really that buggy initially? That’s honestly a bit shocking to hear for me. I did think that Bitcoin was quite solid from the very first v1.0, and has only been “expanded upon” with BIPs ever since. I did not know that such serious bugs existed early on.

Exactly how early are we talking? I had coins in 2009 or 2010. So, back then, anyone could just spend those even though only I had the private keys? And this extremely serious bug was somehow fixed without breaking Bitcoin?

beginner – Greedy algorithms to find minimum number of coins (CS50)

I’m taking CS50, an Introduction to CS, and we’re asked to do the following task:

Suppose that a cashier owes a customer some change and in that cashier’s drawer are quarters (25¢), dimes (10¢), nickels (5¢), and pennies (1¢). The problem to be solved is to decide which coins and how many of each to hand to the customer. Think of a “greedy” cashier as one who wants to take the biggest bite out of this problem as possible with each coin they take out of the drawer. For instance, if some customer is owed 41¢, the biggest first (i.e., best immediate, or local) bite that can be taken is 25¢. (That bite is “best” inasmuch as it gets us closer to 0¢ faster than any other coin would.) Note that a bite of this size would whittle what was a 41¢ problem down to a 16¢ problem, since 41 – 25 = 16. That is, the remainder is a similar but smaller problem. Needless to say, another 25¢ bite would be too big (assuming the cashier prefers not to lose money), and so our greedy cashier would move on to a bite of size 10¢, leaving him or her with a 6¢ problem. At that point, greed calls for one 5¢ bite followed by one 1¢ bite, at which point the problem is solved. The customer receives one quarter, one dime, one nickel, and one penny: four coins in total

Here is my solution to the problem:

#include <stdio.h>
#include <cs50.h>
#include <math.h>

float cents, money;
int ask_money(void);
int dollars_to_cents(int dollars);
int get_max_coins(int _cents, int coin_type);
int min_coins_exchanged(int _money, int _coin_types(), int _arr_length);
int quarter = 25, dimes = 10, nickles = 5, pennies = 1;

int main(void)
    money = dollars_to_cents(ask_money());
    int arr_length = 4;
    int coin_types() = {quarter, dimes, nickles, pennies};
    printf("%in", min_coins_exchanged(money, coin_types, arr_length));

// Given some amount of money, this returns the maximum amount of coins of a certain type possible 
// such that the remaining money is less than the value of the coin type, then it subtracts our money by that amount 
int get_max_coins(int _cents, int coin_type)
    int max_coins = floor((float)((_cents) / coin_type));
    money -= max_coins * coin_type;
    return max_coins;

int ask_money(void)
        money = get_float("Change owed: ");
    while (money < 0);
    return money;

// Necessary to avoid problems with floating point imprecision
int dollars_to_cents(int dollars)
    return round(money * 100);

// Calculates the minimum amount of coins exchanged such that when these coins are added up they are equal to the change owed
int min_coins_exchanged(int _money, int _coin_types(), int _arr_length)
    int _min_coins_exchanged = 0;
    for(int i = 0; i < _arr_length; i++)
        _money = money;
        _min_coins_exchanged += get_max_coins(_money, _coin_types(i));
    return _min_coins_exchanged;

I’m looking for feedback on my code. How do I make my code better and cleaner? I.e in terms of readability, performance, comments, design principles, etc. There’s a lot of ways to approach this problem, and indeed when trying to solve it I’ve tried many different ways but this is my current favorite. What do you think about my solution? Perhaps there’s a better way to approach the problem?

bitcoin core – Brother died and I am sole survivor..just found out he has a wallet. How do I go about getting his bit coins I have no info

I have no info..

Without information, you cannot get control of any Bitcoin your brother possessed.

You need some details of his wallet or of his account with a Bitcoin exchange.

How do I retreive

If he looked after his own money in a Bitcoin wallet on a computer or phone, you need to be able to log in to that device and run the wallet program and enter any password he set on the wallet. He may have kept a note of his wallet’s “private key” or its 12, 18 or 24-word “recovery phrase” written down somewhere safe. E.g. on paper or stamped metal in a safe. If so, you can use this information on a different computer to create a new wallet that controls the same money.

If he had an account with a business that looked after his money for him, you’ll need to find out the name of that business and his login details. It is possible you would find some details in his old email messages.

I have death certificate.

That might be of use if his money was in an exchange and you know his account name but not his account password. You or the executor of his estate would need to contact the exchange directly about this.

You will be contacted by people offering to help you. 99% of these will be scammers intending to trick you into trusting them with any details you find, or who will trick you into paying invented recovery fees but who will never give you access to your brother’s money. Be very very careful.

transactions – BTC coins I did not send sent to blockchain

I used some coinjoined BTC coins from my from my WASABI wallet to exchange for ADA on Godex. I sent coins from Wasabi wallet but had Godex deposit them in my Exodus wallet. It was around 500€.

There was no problem with the exchange with Godex but all the other BTC coins in my wallet that were coinjoined were sent to Blockchain and remain there unconfirmed. I did not send them. The coins are gone from my wallet but I can see them on the blockchain.

All these coins in my Wasabi wallet were not conjoined together and the same time.
They were sent in 7 separate transactions from my Exodus wallet to separate addresses in my Wasabi wallet and then coinjoined separately. Now all these separate coinjoin coins are listed as an INPUTS on the blockchain. Unconfirmed

The BTC coins seen on Blockchain are are Unconfirmed and UNspent


Is there logically any way to “live off of Bitcoin interest” without giving up control of your coins?

This is possible, but not exactly in the way you’re expecting!

Consider what you really want here: is it just an increased number of dollars or BTC? Nope! What you want is an increase in your buying power. Stop to think about the difference here for a second – it is important!

The goal is an increase in buying power, which means you want the ability to buy more tomorrow, than you could today.

Banks pay interest on deposits because they will use those deposits to make investments of their own, and those investments will (hopefully) do well and make the bank some profits. The actual cash money itself doesn’t just magically grow! In fact, the opposite is true: as the money supply grows (unpredictably!), each individual dollar will hold less buying power than it did before. So just keeping dollars stored under a mattress is actually a pretty bad idea: that money will have less buying power tomorrow, than it did today. If the goal is to increase buying power, then clearly just holding dollars is bad, and so the prudent individual will find investments that can increase in value over time. With enough money invested, they can ‘live off the interest’ of those investments.

Bitcoin, on the other hand, is a very different type of money, in that the supply of it cannot be inflated, so the act of just holding coins does not suffer from the same issue of unpredictable dilution that dollars do. If BTC maintains current adoption/use rates*, and society progresses and grows in GDP, then each BTC will accrue more buying power over time.

The difference should be obvious: dollars are a bad asset to hold, they lose purchasing power over time due to an (unpredictable) dilution of supply. Bitcoin does not suffer from this, so a holder might expect their purchasing power to increase over time. Many people call bitcoin a ‘hard money’, as in, ‘it is hard to produce more of’.

So all of that is to say: just like dollars, if you hold enough BTC, you could maintain a certain amount of purchasing power over time, while still living off the nominal increase in purchasing power of your BTC. The actual number of BTC you own would slowly shrink, but this is somewhat inconsequential if your goal is to just live off the interest while maintaining your net purchasing power.

*of course, bitcoin is currently in a young stage of growth, so it is a fairly volatile asset in regards to purchasing power over short time frames. But consider what the situation would be if it were as widely adopted as dollars – that is the more interesting situation in regards to the idea I mean to put forth here. Of course, if bitcoin continues to grow in popularity and use, then we might expect the buying power of a coin to increase, and vice versa.
