but i think investing in currency is more profitable than tokens.
Do you mean to say that investing in coins(that's crypto currencies with their own blockchain) is more profitable than investing in tokens(that's crypto currencies that run on other blockchains)?
Well, if this is what you meant, then I disagree with you mate, if you ask me, I will tell you it's just about the same thing, the most important think here is you being lucky enough to find and invest in the right one,, what ever amount you've made investing in coins can still be made investing in tokens, it all boils down to you finding the right one/project
