After thorough research, I chose to invest my funds to a seemingly booming industry of cryptocurrency. I placed a small amount of 500usd to test it out. Results were promising and I was hardpressed to keep using this service until one day it shut down and all the funds were frozen. It appears that they did some kind of scam. I cannot believe that I fell for such greedy activity.

They did not refund any money but it is now clear that their owner Homero Joshua Garza is about to face criminal charges for his conduct.

Avoid cloud mining pools like a plague - you will never know who is real and who pretends to be one. It is better to invest in things that you know and understand.
