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?
Aside from bitcoin i suggest you to buy Ethereum because it is in the 2nd rank in coinmarketcap. It has a solid project and its smart contract is already existed. The value of Ethereum will increase because of the demand because you need a gas if you create a token in Ethereum platform.
