ETH and BNB are still on my list for my favorite altcoins and that is because I've got some significant investments on them. And I do some investments as well with the other known altcoins but when I am in profit, I sell them as soon as possible. I don't invest to the projects that are shilled to me but if I do, I'll make my time in DYOR so that it won't mess me whenever I decide to buy it.
I don't think because of the high transaction fee of bitcoin will make me to choose altcoins over bitcoin.
While that's a reality about the fee for BTC transactions, I'll still keep mine as well no matter what happens to it but it looks like calming down.
