BTC is a MEME, so it is advised:

1. Participate with money that can go to zero or is not used for a long time

2. Consider taking out your capital when doubling
This depends on each person's risk preference

3. Take profits when the market is good, continuously reduce your position on highs
For example, this round at 120000, all the favorable conditions in the world are in place, nothing new has come up, FOMO has faded, reduce!

4. Buy the dip
This MEME will not go to zero, there are many big players and optimistic people involved

Damn it, if I had figured this out earlier, I could have made so much money.
