Unless you are a very experienced trader, I strongly suggest you not to do that.
Altcoins pose substantial risks, even in day trading: subpar exchanges, vulnerabilities of all sorts, poor liquidity that can damage your profits.

yes, I agree that alternative cryptocurrency is way more risky than bitcoin is so unless you are experienced enough you should not trade alternatives in a big amount.
