Some altcoin that I recommend investing now are Cardano, Monero and Stellar. These are very promising altcoin. Cardano has the perfect technology, it overcomes many weaknesses of the BTC, I believe in the future Cardano will grow strongly. Monero brings privacy, every transaction with Monero is completely anonymous, no one can find out the user information. Stellar has a steady growth rate, and this long-term investment in altcoin promises to bring a lot of money for us.
