Gambling + Loan.
If you can't even afford to spend .002($2) to join a contest, then don't gamble. Asking for a loan just so you could gamble it away?
Plus, you're not even offering any sort of collateral, just a 'promise' to send back the amount after the contest and some 'extra' if you win.
I suggest you lock this thread because this is exactly 'asking for a loan without any collateral'.
1. Buy some bitcoins so you could play.
2. Do some task or offer your service and earn some bitcoin and then play. Or
3. Don't play.
