This is something that can happen and without a doubt you need to be careful, however what percentage of your capital do you want to invest in those coins? Because if it is a small percentage, like 5% or less then maybe it is worth it to roll the dice and hope for a few of those coins to go up in value, however if you are thinking on investing the majority or all your capital then this is a move I would never recommend, due to the high risk that you will be taking.
We have to allocate max 10% for the altcoin list above because most of the altcoin list above I don't know, but if the list above is only ETH and BNB then I will allocate 70% for investment in both because there is no doubt for me to invest higher on both coins.
