I think depending on your preference, if you like safety then choose bitcoin, the profit will be a bit less, but if you like altcoin, it will be more risky and the profit will be higher. The higher the return, the higher the risk. Or maybe to be more optimal you can also allocate your portfolio 50% bitcoin and 50% altcoin, or 70-30. But it can be said that investing in altcoins is not as simple as you think, it's not about picking any altcoin and just buying at low prices and waiting for the bull season to come to take profits. Things are not so simple, a lot of altcoins have dropped 85%-95% but there is no guarantee they will recover even some will not survive this bear season. So investing in altcoin is very risky, it's not like bitcoin, how much bitcoin can fall doesn't matter but it will always be the first to bounce back.
