To be honest, altcoin no longer has potential in the market anymore because of the restraint of big brother BTC. Ever since the Bakk incident made me remove altcoins from my portfolio. Currently, I only focus on BTC and exploit this potential coin.
actually altcoin still has potential but not much, if you invest better don't focus on just one coin, choose a few more to add to the most important portfolio don't too much too. if you invest all your funds in one coin I think is less than the maximum for income, but all that is your choice back
