Hi all,
The 99mining.cloud is a 100% legit website when I was a free user in this site I also think it is a scam but after upgrading my package I got paid in just 24 hours every day.
It is an amazing experience with Unmined.io
They give the fastest withdrawal and increase Bitcoin mining speed.
I got paid in the newest Bitcoin mining service.
Quickmining is change to coinmining now. I think the big change is for security, daily withdrawal and increase the speed of mining. I was started my bitcoin mining process with coinmining and I got piad yesterday.
