What sort of returns should I expect
Investing is easy because it does not require to much time before we can put our money.
as much as you can get if you win, but if you lose, then you can lose all in USD 3000, so be careful when you gambling, especially you have to be good in self control otherwise like i said before, you will lose all in just 1 hour mayber or less.
better you separate your USD 3000 into 3 part, 1st part which is USD 1000 for gambling, 2nd part which is USD 1000 for other investing, 3rd which is USD 1000 part for trading or keep it in your wallet.
