ADA is one of the very potential altcoins, it has a professional #DevelopmentTeam , good scalability, fast transaction processing and I believe in the next few years the ADA will become one of the best altcoin. . But Ethereum is the queen of the crypto market, it is always my top choice, Ethereum is very stable and in the next few years it will grow stronger, maybe it will compete with Bitcoin. I believe Ethereum's price will soon rise above $ 1400 by the end of the year, so right now is a good opportunity to buy Ethereum.
