hashflare is legit so far
roi is about 3 months and obviously the higher the investment the bigger the profit
only invest what you can afford to lose
In the meanwhile, with such a high price 2.2 USD per TH/s and such a high difficulty rising rate 18% every 2 weeks, the ROI can NOT be only 3 months, anyone who want to get involved should do some more precisely calculation. That is my advice for now.
No, it isn't!
It was a ROI of 2-3 months with the 1.50 price and the BTC above 17k. Now, for the 1.5 buy-ins it's closer to 4 months ROI.
Although I like Hashflare I wouldn't reccomend to buy for 2.20! Don't think you will make money at that price. Somebody mentioned that the BTC has to stay above 20K to make it profitable at that price and I tend to agree.
It might eventually jump over 20K but at the moment this is a big gamble.
