It requires a huge amount of luck to turn your $200 to $5000 within 30 days. Imo it's better if you save the $200 and focus on looking at other options to pay your loan. If you have some service that you can offer you can check the
services section. I don't have a lot of ideas in making money but you can check this
old thread it's a guide about making 1btc in less than a week through trading nothing is guaranteed but I hope you can learn something out from it.
Theres no way you can make x25 trading or even gambling
You might get luck 2, 3 or even 5 times, but then you will loose it all
With gambling there's a way but it's not recommended for OP's situation.
Yes you are right, making the price of your coin to grow that fast is not possible because trading in the market needs a huge amount of capital if you want to earn more profit but if you will go on and try gambling then it is possible but the risk you are taking is very high and you might go broke within just a few days.
