❓ASK – Best Amount For 1st Bitcoin Investment | Proxies-free

I’m not sure how much would be best to invest in crypto, if I choose to do so. Part of me thinks play it safe and invest only 20 or so, wait a while, observe the markets…….. then add small increments of 50 or so each month if the market appears to be good. Also, most importantly, when is the best time to withdraw/sell? What are some signs that crypto is at a peak.
