I've seen some advertisements for "lifetime mining vouchers" on a website called CEX.IO, I'm not at all familiar with the website but I'm interested in the idea of purchasing a set gh/s for life I just don't know if it's what I think it is... Here's the listing: http://www.ebay.com/itm/1-GH-s-ASIC-BITCOIN-Cloud-Mining-Contract-Lifetime-Voucher-for-CEX-IO-/161277667314?pt=US_Virtual_Currency&hash=item258ce5e7f2
What I'm expecting is 24/7 cloud mining forever, but that seems a little too good to be true, am I missing something here and what are your thoughts on this investment?
