Update: due to the response from JA Mining, I have used the new link and was able to sign in. My account was still available and correct. However, I did receive an automated google warning that I had signed into a deceptive site. I will update if any problems occur.

Original review:
JA Mining is just the latest Cloud mining service that has, inexplicably, shut down and disappeared. Over the last 3 months I have been testing their site out and was impressed. But today, only a week away from cashing out the “newbie”, $1/day profit contracts with $100, the site no longer can be found. So while it may have been a good site once, it appears to have dropped its customers and potentially taken all of their investments.

So I call it a just another cloud mining scam site. A little better at the game than others, but a scam all the more.
