Come on, you can do better than that. Volatility isn't measured exclusively on a, what is that, weekly chart? Did you really need me to zoom in for you?
I can't buy my groceries with BTC either, but that's because no store will trust a payment method where within an hour the value of what I've paid them declines 10%.
That's the magic of fiat currency.
Put it another way, where'd you get that $400M from? Did you earn it, or get it from venture capitalists? If the asset is such a sure bet, why did the VC give you the money to sit on instead of investing it directly themselves?
And why is it that companies that pay dividends tend to do better in the stock market and be more stable? Essentially a dividend is admitting you have more money than you know what to do with, so you give it back to the shareholders rather than getting distracted from your core competency.
