At this point in time, I don't believe Hashflare belongs with the take the money and run group. People who are having payment processing problems have had things corrected after a long delay - they just don't come on here to say it.
Most of the people saying it is a ponzi scheme are busy investing in ICO pyramid schemes.
You can accuse the ICO, but see that hashflare has made some promotions between the months of September to November, you can say that there is nothing wrong with a company makes promotions. true, But cloud mining has the time running against them, they spend a lot of money with electricity, maintenance of mining equipment and payments to their workers. I do not see space for them to make promotions. After the promotions they have increased the minimum withdrawal value to 0.05 btc, this is a huge value and for those who have invested little, they will not have 0.05 btc to withdraw their coin even if they spend years, that is, they can only offer their coins for hashflare. This all seems to me that hashflare collapsing and to save the company from collapse are using unfair methods.
