Cool service, but I don't see how I could make a profit with this unless I'm banking on bitcoin prices rising dramatically. If I'm counting on the raise in price, I feel like I would make the choice to invest directly in bitcoins.
$1900 could buy me about 95 bitcoins today. 1 Gh/s would give me about 1 bitcoin a day at the new difficulty taking effect in about 3 hours (about 868,000). So if the difficulty stays _completely_flat_ for the next three months, I'll only make 90 bitcoins. But we know that the difficulty is rising, so the most we could count on is about 50, and even that is pushing it.
I don't me to disparage your services on your own thread, I'm sorry. But the numbers just don't add up for me. Does this make sense for anyone else?
Direct buying is clearly an option, but that doesn't necessarily mean no one wants to mine, albeit the difficulty is rising.
One other point:in many countries outside US, buying BTC is not as easy as you can imagine, at least not easier than direct mining.
