The fastest way to make money in crypto is by trading but as we have known there are two method of trading the long term trading and short time trading. I will advice you learn more about short time trading very well before you start trading with bitcoin.
And I would not watch short-term trading at all because it is very risky. Look at the long-term, for example, Ethereum or BNB or NEO, see what interest they gave, it is much stronger than short-term trading!
