Half of these sound like legit pyramid schemes rather than mining groups.
Be careful newcoiners!
I use HASHflare and have since June. Approaching ROI now at the end of month 4. Not bad with 8 months to profit.
Unsure the final results but so far so good.
Anyone curious hit me up and I will share more details.
Thanks!
