There are so many different types of coins nowadays, but I don't even know how I should choose anymore. Do you guys have any good advice?
There is no end to advice on this matter. Because everyone's prediction is different. You have already received many suggestions. But there is no alternative to your own research. But the coins I prefer to invest in are BNB, ETH, TON, SUI. These blockchains are currently being used more. As a result, I think the market value of these coins will increase several times.
It seems I also have the same preferences as you. Layer-1 coins like SUI, BNB,TON are the coins that will get new ATHs in the future and I think these are very worth investing coins. I really like layer-1 and I think if there are other layer-1 projects I will also try to invest in them.
