DCA $500 a month for 10 years

Hi everyone, just wanted to see people’s view on DCA in crypto long term. The portfolio is 60% Solana, 20% Ethereum and 20% Bitcoin. The end goal like everyone is to make the most amount of money in this time. I plan on just holding it (not trying to time the market) and consistently buying every week. This is for the long term. Let me know your thoughts.

What do you think about my portfolio? ~ Changes you’d make

Do you reckon the altcoins of today will even be a thing in let’s say 10 years?

Should I just 100% focus on Bitcoin?
