Altcoin is much profitable then bitcoin and Ethereum. All altcoins have possibility to pump more then 100% in one day but bitcoin or altcoin haven’t this chance. but here altcoin investment is must risky. Even then i like Altcoin investment coz of my little money.
yes, altcoins will indeed be very profitable in some market conditions even the profits will exceed 100%. but the risk of loss will also be the same.
even if the amount of my money is small, i will still choose ethereum or bitcoin. I realize market conditions are unpredictable, sometimes i also choose to keep some new altcoins. but that's very rarely I do.
