How can we retrieve almost all real-time cryptocurrency information (prices, transactions, live prices, block information, wallets, etc.) to develop new cryptocurrency statistics and reference data (such as Binance)?
We can use the API of blockchain.com for BTC and LTC and some other references like chain.so, block.io etc., but what do we need to get all statistics for all crypto currencies?
I mean, how does Binance get that information? and where can we get it?
I know that there is a website selling this information and their own APIs, but how did they come up with that? and indeed, how can we get that information free?
