PBmining is the best priced offering by far but it's also a ponzi scheme.
Before they implemented a coinmixer it was easy to see the coins go directly from new customer payments to the "mining earnings" wallet.
There is no way that they can give you a 5 year contract on any hashing power right now with no maintenance fees. The power bill alone would sink them several times over. I believe "Ponzi scheme" is putting it mildly.
Also, it is located in Canada but will not sell to Canadians. Go figure.
^is it really? I saw that disclaimer on the site but never considered it was actually a canadian company.
That just ranks of the mentality that someone scammed outside of canada will have little chance of retirbution, whereas if a canadian is wronged could easily take them to court
PB mining has a long standing good reputation according. I can't buy from them tho -as I am Canadian. So I have been doing research on other cloud miners. I use
http://www.rigwarz.com/ to help me find them. The AMHash1 - Bitcoin cloud mining contract looks like one of the best deals going right now. ASICminer's latest hardware looks to be as efficient as Bitmain's.
My concern is I have no experience with Havelock Investments. If any others on here can vouch for them, that would likely help my decision.
