Hi, Can you please tell me the which type of altcoins we should buy. Like:- which has already product established or having a strong development or backed by someone very powerful(big companies) or whose idea is best or any other reason which we should consider while buying the coin?
Strong development progress, future roadmap, reliable team, good whitepaper. And the last should be the coin must have a big community behind it to support the development progress of the project itself.
I think that you must do in-depth research to take a conclusion about how good the coin.
But the fact that community support is having a big role in the project. because at the same time it helps the project to grow in the future.
