I can't believe people pay for 5 years worth of mining.
Most companies in bitcoin world barely can stay active for more than 5 minutes.

They don't. There's no mining here. Just mixed coins.

Although that might be true, I trust PBMining, and I believe that they are legit.
Even cex.io has been around for some time.

Some lovely basic math, cheapest area in the US for electricity widely agreed is Washington at around $0.10 per Kwh.

Currently ASIC hardware efficiency is around 1w per GH/s, things like Terraminers much worse anyway so anyway 1w per GH/s... 1000GH/s = 1TH/s at PB's current price around $2000 ($2 per GH/s)...

Cost to run the TH/s for 5 years in electricity alone in the one of the cheapest regions in the world... with zero magical free hardware, free cooling, free giant mega mine, free insurance, free staff just electricity is $0.10per Kwh x 24 for the day x 365 for the year x 5Years because that's what they say.

This is... and please work it out... $4380

Regardless of payouts. Irrefutable evidence they are not doing what the claimmmmmm. Boom

This is not opinion, oh I think they're dodgey blah blah blah... It's mathematical fact.

Current investors better get busy on the Affiliate program to keep getting payouts.
