A few days ago I signed up on exabit.co a Bitcoin minig site where you can buy hashrate power and earn satoshi from mining. The platform is currently giving a hashrate of 50 GH/s to each user who registers, up to a limited number of users.
It is possible to increase the hashrate by purchasing additional mining power and through the Bounty Program campaign, through some simple tasks such as publishing reviews of the platform on Twitter, Facebook, Youtube and more.
I have been registered for a few days now I collect my satoshis without any effort, with the free power of 50 GH / s I get up to 500 sat every 24 hours. The quantity is comparable to a faucet but in this case I am not obliged to do anything. I register and then it does the whole system. The minimum withdrawal is allowed at 25k satoshi, I have never withdrawn and therefore I am unable to provide you with feedback on this.
The platform, however, is very nice and easy to understand, if you want to try it out of curiosity. At the moment I don't recommend investing money, always do your research. Be careful and have fun
