2 years ago I lost 0.5btc (my account on ore-mine).
This HYIP has lived for many years and all the time it has been steadily paying and was the most reliable of all that I knew.
Because of this, by the way, I have a negative ooputation here, and yet I am one of the victims of it. I managed to get only 6 million for the whole time, everything else either put it back in ore-main or lost on their roulette (in total they lost about 2500000 satosh).
I created my post here only to warn about temporary contracts.
The return on investment is 100% at current prices of 26-27 months, which is not 24 months.
