Hey xian, you really need this drlukacs on your side - he's an ace litigator and will get you back the potential $15k you lost due to your inability to hold back you tongue...
Actually, it was partially thanks to you. In 2012, BFL entered into a forward contract to provide future goods with Xian in exchange for capital upfront. This is a very common occurrence in agriculture for crops, fuel, equipement, seed, fertilizer, etc. It is also common in resource extraction industries like mining (how apropos).
As you noted, these contracts increased dramatically in value since they were first purchased in 2012. You also noted that Xian should have been able to sell another forward contract for the delivery of his units to a third party for a healthy profit. BFL unilaterally terminated the contract, but they did not compensate Xian for market value, only the original face value. BFL then sold the rights to Xian's units to someone else for a higher return. The whole point of a forward contract is to obtain future goods at a fixed price. If the seller could unilaterally change the price at their whim, no forward contract would ever be worth entering.
It should be quite trivial for Xian to obtain a remedy. The courts would probably not be involved unless BFL was unable to pay. It is possible I suppose, that BFL would fight it for pride's sake. I really can't see them winning. This is a clear case of breach of contract.
