I agree with you on this, altcoins are more profitable than bitcoin base on the fact that bitcoin doesn't move so fast like altcoins that can turn 100% within 24hrs
For altcoins to increase to 100% within 24 hours, I believe that they are shitcoins and you will definitely lose money if you invest in them. Investing in altcoins is a risky investment option because the price could collapse anytime soon, current investors are a lot more careful than before and safety is the first choice.
