So, do the math. Or look here:

Ask yourself this - for a company that went up 5000% from the IPO, would you consider a fair value overshoot of a couple hundred percent unreasonable? (Don't forget that USD/BTC is up 10x from the IPO too).
I'm sorry if you lost money, but if you do not base your stock trades on facts, math and logic, you are a gambler, not an investor.
At your target price of 1.5 BTC based on projected net profit 10 years from now, 2 BTC is a good deal considering the dividend payments which will quickly add up to greater than 2 BTC even if the price goes down to your target.
You understand the dividend payments are the profits that don't get reinvested, and thus the 10 year dividends cannot exceed the 10 year profit?
The point of that link you quoted is that the 10 year profits are unlikely to exceed 1.5 BTC.
