I've been using this site EOBOT for maybe two weeks and I have a specific strategy I'm following. I started with by using dogecoin from various faucets.
If you see, I already have 1.86 GHS and I'm building up my GHS for the next few weeks. Without spending actual money, I've built up almost 80 cents worth. I also have 10 cents that I just transferred from my faucets and I'll have another 10 cents by tonight.
I like this site because it's been around for years and it's reliable. They give you 1 doge per day when you log in everyday and they have a faucet that you can redeem everyday as well. We'll see how much GHS I can get within the next few days with this site.
