We should always have some cash and BTC in our vault (I think it's 1/3). In fact, BTC is also cash, but we can also hold BTC separately. Cash will always allow us to make new purchases. Sometimes the market doesn't move according to our expectations and surprises us. In such periods, we need to lower the average by making new purchases. Otherwise, our trades may be off the mark.

The other 1/3 of the money can be invested in major coins. The rest can be in new projects that are riskier but have the potential to make more money.

Of course, I would like to emphasize that I do not want to give investment advice. I only wrote general things that everyone can agree with, I can't do more than that...
