Hi guys, i need 0.003 btc and i will give it back to you 0.02btc in 1hour im willing to give up my bitcointalk account if i didnt pay . Thanks in advance 
Provide a collateral in ZEC, ZEN, ETH, LTC or Dash for 120% of BTC needed value and I will lend you the amount required. But somehow I doubt you will.
You should collect 120% of the BTC returned.
