Payment proof about Ore-Mine.org have not been confirmed yet even as regards the signature program on going here.
Website is online since August 2014. Payout so far 1471 BTC. (Statement of the operator).
The corresponding thread is 40 Pages long and don't see a single "not paying!" message.
However, several that has been paid.
Here is my Overview:
The website has a rating as 'Gambling'. The risk is in my view absolutely identical to each other Bitcoin investment.
Never invest more than you are prepared to lose. The usual approach.
Can only say from my perspective, no problems so far. Of course, I submit no guarantee. That would be simply a lie.
However, because someone was kind enough to help me out of my short-term lack of money, I'm freezing this offer for now.
With option to repost / reopen if if it should become necessary again.
Thank you for your interest
