One random site to kill the time..
You start with 50 FGN tokens,which you can gamble on slots or spend at lottery.
They have faucet,you can claim FGN tokens there,without time limit.
FGN tokens are listed on Poloniex DEX,with FGN-TRX pair.
What is different with this site?you can't deposit anything,deposits are not allowed.You can only withdraw.
So this makes perfect time killer,and you can earn few "satoshis",you can't lose,because you can't deposit.
