one should be careful what sites to invest in tho.

yes, the free ones I've posted have nothing invested, only working with the free hash they give upfront

i just checked out everyone of these sites and DO NOT INVEST YOU WILL NEVER GET A WITHDRAW not even form the free power he is just spaming referals

I wouldn't say I'm just spamming
I found sites that give free power, I've stated I have nothing invested in them.
Whether they ever get a withdraw, I'm not sure. But if I get any referrals I'll get there faster and I can let you know if I do get a withdraw.
