Bitcoin was and will always be the best choice if you want to invest in cryptocurrency. Other altcoins are centralized shit. You can not convince me that they are good. Not gonna happen. I got scammed multiple times in the past after investing in alts. Now all I care about is Bitcoin. So the thing that you have done is very wise in my opinion. Others may say that other alts do give you profits. But how much are there? Doing all your work to find the best one while it is sitting right in front of you. I can not choose anything other than Bitcoin. History is the best teacher. Learn from it and you will know.

Bro, don't make the same mistake I did. My trust wallet got hacked once and all my funds were gone. Every time I sent a transaction, it got redirected to some random wallet address from my wallet. So software wallets are always at risk. I will recommend using hardware wallets to keep your funds safe.
