As stated on the thread:
We are giving away total of $7500 to 50 new players who deposits $250 or more and play at least 10 games with minimum 500 Bits Bet on any mine field they desire.

I do agree on what that guy commented about signed messaged of funds or will be doing some escrow. Depositing $250 isnt really that something small
for people to put on for a site that had just recently go back to life.
