I have a 8x 1080Ti rig and I'm also using genesis, I should be able to answer your questions:
- Genesis is not a scam, but we are all getting tired about the fact payouts are not regular... I'm still waiting a transfer of ETC since 19th of Sept, and I got one for the 22nd... the service is lacking a lot...
- The return is actually a bit lower than mining yourself, but I'm ok with it as I do not have to check the mining every 3x2
- In June the company got hacked... when you sign up with them they tell you that if something happen they will not refund your money, so you hold 100% of the risk
At today, to be 100% honest, I'm putting my new investments into Bitconnect, even if there are more people saying it is a scam, so far they have NEVER missed a payout and you get your full ROI in 3 months, while with a Rig you have 10-11months and with Genesis 12-14 months.
Hope it helps!
