Genesis mining is investing of your crypto coins in exchange for their mining power in hashes(I really don't know if it's really true to what they are claiming) and they are running for how many years now, I think most of the genesis mining investor is really taking a profit with their referrals. If you want to know what is the benefit in investing in genesis mining then you must go to their website and know about it.

the difference of crypto currency trading and mining is that in trading you must be well knowledgable to avoid massive losses in your investment while in mining you are just waiting for your hardware to do the hardwork for you but long term return of investment nowadays.
