Is it really necessary to exchange the altcoins in your hands for BTC?

Personally, I think that if you have a large amount of U and are a long-term player, then there is no problem for you to make a layout of Bitcoin, and the short-term rise and fall will not have any impact, because the general trend is going in that direction, but at the same time there is also a problem, that is, how much can BTC reach in this round of bull market, will it be 100,000 or double? Personally, I expect that doubling is already a very ideal state.
