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.
If you like Altcoins for a lack of money, then you immediately love Bitcoin, just because you don't have enough money to buy them right now. So there's no need to deny that here where you say Altcoins are much better than Bitcoin in terms of price movement.
You need to know that any Altcoin will not be able to pump much when Bitcoin starts to crash in the market, you can see the evidence for yourself in the market, both when Bitcoin is increasing and when Bitcoin is declining.
