I don't have any secrets about the OP's question, but I just have a piece of advice. If you expect big returns when price pumps occur, then you should be ready to invest as much as possible in bitcoin. What you want must be commensurate with your efforts, meaning if you want to fly, then have a plane. So own bitcoin first and increase your portfolio over time, it can help you get the returns you expect.
This is what many do, but you have to know how to apply it because normally the ideal is when you know that you have the bullish confirmation of btc and once there is this confirmation and there is the first correction is when you buy the alts, and when they increase in price and then you have very good profits and that is when you should buy btc, because it is known that the btc will rise in price, some people do not buy btc but leave it there until the alts start to drop in price and they get the most out of the alts , this is a matter of decision between people and the investor.
