Actually if you have 2-5 hero.member account, there's not too hard to get 10btc in 2 months.

How can it be done? I am sure it can't be done from signature payments as most campaigns pay only 0.1 btc per month for hero members.

We all hope that Primedice sig. campaign will be launched soon.
In their previous sig. campaign Hero Member could earn up to 0.4 BTC monthly.

Wow. How much do people sell Hero Member accounts now? 0.3 BTC?

It feels like I've been newbie for ages. Kinda tempted to buy a higher rank account.

I think >1 BTC. Because i ever seen hero memmber accounts sellout on 3.3 BTC.

How much i must invest? ROI?
it's impossible Roll Eyes

Today collapsed Hashprofit and Hashie "cloud mining" services.
Just before collapse Hashprofit had ROI about 1 week

So it's better to search some safer way to invest money.

How much you invest?
i used HP too, but i'm not invest, i just get kh/s from reff.
