experimenting with the calculator lead me to the same conclusion. too bad...

but thx for the help and saving me money.

Hi everyone

If this question has been asked before (and i'm pretty sure that's the case o.O) i'm sorry for this thread but i wasn't able to find satisfying answers on my questions so i finally decided to register and post this:

I've been browsing this forum and several other websites for a couple of days now and am willing to invest in mining equipment. Is it possible to make relatively correct assumptions on the approximate ROI if i, let's say, invest a 5-digit amount in equipment and consider the increasing difficulty? As far as i'm informed now it makes little sense to pre-order from BFL and maybe receive a piece of hardware in 2015 and gpu-mining seems to make no sense as well.

I came to the conclusion that buying USB asicminer erupters for 2 BTC a piece seems to be the most logical solution at the moment (?). Assuming that i'm willing to invest e.g. 10.000 € (~142 BTC @ 70 € per BTC) i could buy 70 erupters (1 for 2 BTC) hashing at 70 x 0,333 MH/s = 23,31 GH/s (equipment and power supply costs etc excluded). Can i hope for an amortization of the costs in 3/6/12/x months or will the rapidly increasing network hashrate leave me with hardware that can barely compensate for the power costs?

Thoughts? Recommendations? "Professional" advice might get paid.

Thanks in advance
