I want to trade altcoin but I don't know the very coin that will exist and have future. I need guildance to take this step
For now the coin that has potential is the Cardano coin. With the launch of new smart contracts, most projects will switch to using Cardano smart contracts. The current price is still very low, and I expect the ADA coin to hit $10 in the near future. The presence of smart contracts is very influential for the crypto.
