It is not free. You will pass KYC test to have a chance to get free $50 BTC opportunity. this is risky for 50 dollar my KYC is worth more.
bitterx need to provide legal guarantees that this data will be erased or do upon request.
And the thing is Opportunity meaning now all will Surely take that 50$? because if does for sure all the Bounty Hunters here in forum (that Lives in the supported countries) will Take this chance to gain 50 bucks because some even take a chance with much lower offering as what i've seen in the past. 50$ for them for KYC is already a very decent amount.
But of course me? no will never risk my details just for that amount.
