in my opinion bitcoin and altcoin can both provide profits in the future, and I think it's just a choice, bitcoin is a priority investment for every crypto user because bitcoin has great potential and is very promising, while altcoin is an option that can give you additional income.
Bitcoin is sure, altcoins are difficult because there are so many altcoins. If we choose the wrong trend during this period, our assets will lose a lot in the future.
Here I will talk about only one point, comparison of Bitcoin and Altcoin longevity. Note that Bitcoin has been alive in the market for a long time and has not faced any problems yet. But altcoins are constantly being born and destroyed from the market. So if you want to invest then definitely choose Bitcoin and keep your money safe.
