So I was pondering this for a while now and decided not to get into debt and not to reserve one.

Bitcoin difficulty has grown exponentially during last couple of years. More and more powerful devices are released with faster hashing speeds, but I think that ASICs made it all so much worse. I believe by the time May batch is released difficulty of the btc will be in a 10 billion ballpark. And thats about $2.000 a month profit if even that much. For some its a lot. But considering that you have to invest a lot in the first place and you will have to run that thing for 3 months to get your money back, and considering that difficulty will increase even more I don't believe its worth it in the long run.

What I am thinking is to focus on Scrypt for a few months and then see if they start taking preorders for next tier of BTC devices. Its possible that I'd rather pre-rder one of those next tier even faster toys.

Am I wrong in my conclusion?
