"Hah, good question! I only have one referral, but I managed to amass that mostly from the bonuses, daily dividends, collecting from various faucets (there was one that was particularly lucrative (CoinSpark's demo asset faucet ;)), at one stage - and I've had good results from MoonBitCoin, and various rotators), and doing some trading, and mining on CEX, over the course of several months. Until recently (I decided to take the plunge, and go all-in on ReddCoin, since it's currently cheap, and ShapeShift.io works so well :)), I was using QoinPro as my "daily driver" crypto wallet - so all those little bits soon add up. :)" - Tyson Key
