HashProfit.com was so obviously scam.
Each time I went to their site, there was a warning that their stock was almost sold out, and the nex day they just came out with millions of new stock
And they had unbelievable deductions like 55%, 65% and I even got an email providing a 75% OFF coupon
LTCgear Chris, is my favorite scammer. You can't buy anything cheap from him, you gotta shoot a grand to join the club
He even didn't care about paying someone to set up a good looking and well functioning website with automatic payment script.
ROI went down to 2 weeks sometimes
and his "bye bye referal system, I can't pay the ponzi anymore" coupon was %49
When I warned people, they called me a jerk at the forum.
BTW GAW is scam too.
Some of their hashlets stopped paying.
I had 1 ZenHashlet (10mhs scrypt), It was paying about 5000 sats daily and
it started paying only 1 sat daily right after hashpoint conversion to XPY and XPY release.
That is definetly scam.
GAW and LTCgear has fellow cult members, I won't feel sorry for them at all.
You have Hashnest as a legit company on your list, but I have to warn you about their customer support.
It sucks and they never care to interact with their customers.
You should add a customer care evaluation in this scam measurement.
You don't get your payments at hashnest, you got no one to complain or ask for help there.
Go check their talk and see the unanswered "I didn't get paid" treads.
Be also careful about legit companies, if BTC price keeps going down and difficulty up, they might unintentionally turn into loss as well.
