In the last bull market, I had a friend who made millions with just one currency, ksm.

He has mastered the rules of ksm's short-term market washing, and has not looked at other coins in the whole process.

So if you have a coin that you like, keep an eye on it, understand it, and fall in love with it. Only one coin is enough in the bull market, and it can take you flying.

In fact, speculating in currencies is like falling in love. As long as you are dedicated, you will definitely get rewards.
