There are a ton of professional Genesis-Mining shills out there. Don't fall for them.
If you think about investing: Read this carefully!
So, if you want the short story: Just avoid cloud mining in general, including Genesis-Mining.
As I stated before, I never upgraded my contract and don't accept referrals, so this is fully unbiased data.
After 6 months I got only 36% of my investment back, payouts are even lower than on my first day even though Bitcoin's price has 4x by now.
If we expect constant rises in bitcoin-hashing-difficulty but a less quickly growth of BTC we can be sure to never get our investment back.
Right now the date to ROI went from initially 10th of April 2018 to the 8th of December 2018, tendency towards infinity (= NEVER).
So for everyone who doesn't believe it: I have empirical data that cloud mining has a high chance of losing parts of your investment.
My personal advice: STAY AWAY FROM CLOUD MINING
Just holding BTC will probably be MUCH more profitable
Here are all interesting graphs:

I will make an update in maybe 3 months or if something interesting happens... until then: Just make sure to do something useful with your money. Something that is NOT cloud-mining.
