I've been collecting diamonds on CoinMarketCap for a while now and I did grab a couple of vouchers.
However, the quality (and quantity) of rewards has been going down the drain for the best of a year now.
There are fewer rewards, and they're quite shi**y.
Not only that, it seems there are also technical issues.
Earlier today, I tried getting a $50 voucher for Travala.com and the operation failed multiple times.
The page would go blank and it just wouldn't work.
Does anybody know what's going on? Is it just me? Cheers
