Re: [ANN] - U.CASH [UCASH] Initial Bounty Offering (IBO) Now Complete!
Referral program at the invitation of friends is working or not. 
Not, sign up bonus is still active. Referral bonus is not due to scammers abusing the system. All new sign ups have a 30 day hold on coins due to the same reason. Scammers abusing the free coin system
This is how the ucash scam works. First they make you open a wallet and give you coins, and then you can not withdraw the coins. With the coins lock up in your walllet the price will go up, and then they dump the coins that they have on the exchange. They also ask for your ID to get your information, to open credit in your name, when they shit coin fail. Fools wake up and smell the coffee.
I got my free coins with no issue. All made from referrals, 11000 coins. I never sent in any ID.
Allot of scammers got a bunch of free coins. They are trying to sort it out and recover those coins. Causing transfer to be slow. That is the official word from them.
