Please explain to me where having a 4.3BTC share in Asicminer will pay for itself in a reasonable amount of time? 4.3BTC / 0.025BTC per share per week = 172 weeks... Why shouldn't LabRatMining bonds be worth the same ridiculous mark-up as Asicminer? You're missing the point that some people don't want to have to host hardware and want to enjoy the benefits of mining. I'm not only offering you the benefits of mining, but at a 7 fold rate compared to most other bond issuers. You have to consider the fact that mining isn't a sprint, it's a marathon. Don't ever purchase anything looking for it to pay itself off in 2 weeks...
Because Asicminer is not issuing fixed MH/s bonds, they keep adding hardware to maintain a minimum stable network percentage. It's the network
percentage represented by each share that guarantees its value, not hashrate. On this scenario, with Asicminer, you have a minimum guarantee that when you want to get out, your shares are worth at least the price you paid for them first.
LabRatMining bonds, on the current terms, are losing network percentage every time the network grows, since they represent a fixed hashrate, so their dividend income and their intrinsic value keeps going down, just like any other offer out there that offers a fixed MH/s per share.
There are cases where fixed MH/s shares can be profitable, depending on the network difficulty rise, as they are most profitable when difficulty is almost steady, so an investor can buy and get more in dividends than the share decreases in value, during a specific time-period.
