Maybe you could do it but you need to have a huge capital for example you could get a small profit and fix the amount that you want,
If you want $50 then it depends on your capital for example 1% profit in $5,000 but again it would be risky specially in this market.
There is no difference between big and small because day trading is always risky and you need to face it in order to make profits. It depends on the coin you chosen it for buying and trading in the market.
