Actually, as I stated. The loan will be paid back in BTC, not USD, as the funds will be used to purchase bitcoin mining rigs. Of course this means that the purpose is to mine bitcoins not USD. According to the terms that I stated the loan provider would not only get back their 100+ BTC, but also get an additional 15+ BTC. Using your figures that would not be $200,000 it would be $230,000 which is allot different than $7500. Your estimate on the value of BTC at the moment is close enough, but, if the value declines to, say, $250 and stays there for awhile you'll have to wait for another day to see your $200,000's. No one really knows how much bitcoin will be worth in the future, could be more, could be less. But I can more or less guarantee the amount it is worth right now, and buying mining hardware with the price of BTC being as high as it currently is would be like receiving a REALLY BIG COUPON towards the purchase of mining hardware. This makes investing in mining hardware a very profitable venture, but only at BTCs current exchange rate of ~$600/BTC or higher.

Now it is your bitcoin, so you do what you think is best for you, I could not fathom holding a grudge against someone for doing what they want to do with their own property.

So, enjoy your stash of bitcoin, maybe if you hold onto it for another 15yrs it might be worth a billion dollars! Lets hope!
