No books, learned everything from Youtube since the 2017 bullrun.
I used Coinbase to dump the tiny amount of cash I could spare, then moved it to Binance mainly to trade alts, had no clue what I was doing, 2018 crash hit, so dumped everything into BNB (Binance Coin, which had no use at the time other than reducing gas fees). I focused on work and smashing plates (I was still working for the man at the time), then came back to crypto in 2021 bull run.
To my surprise, my measly £250 in BNB was turned into around £12000 which I put into other coins. I've since kept a close eye on crypto but never day or swing trading. I'll take profit and accumulate where I can, but TA is not my forte and I don't care to look at charts all day. It's easy money if you have a set-and-forget approach IMO.
