Re: Antminer S5, a good idea ?

Better to buy 1155GH/s from Hashnest

www.hashnest.com
Antminer S5
Power: 0.51w/GHS
Maintenance Fee:$0.001175/GHS/Day

Then you see yourself, is S5 profitable or not.

I couldn't understand that site plus apart from bitmain, I am not going to any coinflare-slowed website.

Cloudflare is a great service. Not only does it cache websites locally for everyone in the world (rather than 400ms ping to Chinese servers), it provides DDOS protection. Bitmain and several other Bitcoin services are under attack because they did not pay ransoms. On top of all that, Cloudflare does it for FREE.

Cloudflare is free ?

Yes, the vast majority of features are free (including the local geo-caching and DDOS protection). There are premium services you can use to further increase website loading speeds including various forms of compression, but I've never used or needed them.

That's nice !
