Sorry for my bad english.
It's work. I have sent the 17th march 0,0005 btc and have received 0,00055 btc the 18th.
So in fact, I have lost satoshis because fee of the transaction is 0,0001.
So the site work BUT FOR THE MOMENT.
And I can't dare to sent too much satoshis.
sorry to hear with that.. yeah if you choose wallet blockchain you may loose satoshi if you invested .0005 because of blockchain fee.. and thats not our fault
