Hi guys, do you think investing in altcoin futures is a good idea? Which altcoins do you think are best for this? I appreciate all the help

I want to believe a lot of people already said you should Invest in Bitcoin instead. Investing in altcoins isn't a bad idea, but there's a way better idea and that's investing in Bitcoin. More expensive, Way risky, and more profitable.
To be honest,the only way I invest into altcoin is through mining. Anything involving money, to me, should go into Bitcoin.
