Generally speaking, IMO, buying bitcoins and holding them is usually better than buying mining gear and mining with it.
So the real answer is still no, there currently is nothing I can do with my BTC that is better (more profitable) than simply hoarding them.
Right?
Lending however no real business is going to take loans at 200%+ APR.
We have borrowed a line of Credit at 0.5% per week. Our creditors have enjoyed a return on their capital. Even 0.5% per week is kinda unrealistic but given all the Pirate nonsesne and unrealistic demands of creditors we had to go that high to compete. When we renegotiate it likely will be lower.
In our business we can use the LoC to allow instant trades without tying up our capital or being long huge amount of BTC. The cost we pay in interest is worth the utility we gain. At "asinine" interest rates the utility isn't worth the interest.
