No one has ASICs yet, and the difficulty will be pumped up to at least 5x what it is now in a short period of time. So take that 309 BTC and divide by 5, and you get an idea of what your earnings might be a few months from now when you actually receive an ASIC purchased right now.
Still a good deal IMO, but others have projected difficulty quickly going up much higher than this. And because ASICs are so cheap to produce, the same machine you see selling for $1,300 right now could be sold for $50 next year, you never know. If that happens, many more will buy, and each one will see that much lower of a return on investment.
so, the window of opp is sooner, not later. Actually, even with 80% reduction (60 BTC's/mo), I would still make the same money as my current salary (I work in Argentina and get paid in pesos). Although I was not aware that the ASICs were not even shipping.
Are the people that preorder and
pay for an ASIC just sitting around waiting for their ASIC to get built? That would suck... for me the bigger problem is getting that puppy into this country.
Yes, the window of opportunity is sooner, not later indeed. Unless you consider the possibility of a significant price drop, which I don't believe is out of the question. There ARE multiple ASIC companies, and they are competing with each other. It could result in price wars that drop the prices by half very quickly.
And yes, everyone is just sitting around waiting for their ASICs to get built at this point. I imagine many more will order once people start receiving them.
The volatility of the Bitcoin price is also something to consider. Earlier today, we were at $19/BTC. Now we're at $16/BTC. We've seen a drop from $32 to $2 in the past. Basically, the income potential is there, but it is not 100% reliable either.
Also, some people say the ASIC companies are scams. One of them already went bankrupt and is refunding everyone's money. The next might fall without refunds, you never know.
All of this said, if I had more money, I would throw it down in a heartbeat on more BFL mining machines. As it is, I have two of the SC Singles on order.
Problems in your plan: 1)no one has an asic so far 2)once they will receive them, expect difficulty to skyrocket. 309BTC per month? Yeah sure more like 10 after asic hits the market.
Na, it'll still be a lot more than 10 BTC a month for quite a while after ASICs are released. Without a significant drop in ASIC prices, it'll take at least a year (though I'd say more likely three) for difficulty to creep up to the point where 60 GH/s only makes 10 BTC a month.
