There are a lot, but I wouldn't recommend quick ways of learning cryptocurrency trading because without a comprehensive course that can enlighten you with significant knowledge that you can use to become an efficient trader. A lot of people think this isn't necessary and trading is very easy but you wouldn't want to know what happens to them after some time of getting into the market.

So, try to do it by taking your time, learn as much as you can but don't be in a rush. I know that you might be doing this because you want to make use of the current market situations since we are having a bull run ahead, but believe me, you will be much better with it if you don't rush it, and by the time next bull run comes, you will be a very good trader.
