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?
I have a thought if there are several altcoin types that we should buy the altcoin which has a little supply, has a clear market, when sales are high ico and most importantly the price is always stable. that's my opinion to a good altcoin.
