I suggest to buy bitcoin, the bitcoin price is changing dramatically but let's calculate something 5,000$ % 220$(price of btc before some hours) = 22.7272 BTC. And selling this only after 9hours when the price was 230$.

22.7272BTC x 230$= 5227.2727 USD.

You see the profit now?

5227.2727 - 5000 = 227.2727 USD profit in just 9 hours.

P.S i didn't included any fee from exchanges.
