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.
A lot of lesser known altcoins have very few people participating in them and thus either has most people buying or most people selling. That is actually how you see those rapid crazy 100% gain and 100% loss charts: if everyone is buying...of course the price goes up.
