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.
Going by your apparent lack of understanding as to realistic expectations along with pumping
that long-since outed scam in your sig, I'd say your best bet is to chill out and spend some time reading and getting up to speed on bitcoin, investing, and the other concepts in which you're interested before you take any actual plunges. Seriously, it'd be a good idea.
