I can vouch for progressive mining, I hold contracts there and they are paying, except they are not very clear about your equivalent hashing power and only show u the company's hashing power.
How much do they actually pay for each quote?
I have 25 indefinite contracts with them, costs about 12.5BTC, last payment was around 0.053912 BTC
Sorry, for late reply, but if you/any other progressivebtcmining holder reads this may answer.
What? 12,5 BTC investment and last payment was 0.05? That´s quite shocking to me.
Why do they write about payouts of 75% then? So it´s by far not as lucrative as I thought. I really believed they`d pay me 75% of my investment every 2 weeks.
