I get annoyed when people think of coins in terms of bitcoin price and judge their investments as so. I dont keep my money it bitcoin - I keep it in a bank where it gains nothing, so any gain i get is positive. Judging an investment in any crypto through a bitcoin lens is like saying investing in facebook is bad because amazon went up more...no it isn't it just wasn't the most optimal but it still gave you positive returns.
I understand your logic but I don't agree with you because I am not buying altcoins with fiat but I am buying them with bitcoins. So I'm actually risking bitcoins, not dollars, so profit should be measured in bitcoins. Because if you didn't make that investment, you would have kept bitcoins and they would be worth more so you made a loss with that investment.
