I don't have $10,000,000 worth of bitcoins.  But given the 5-year trend in prices, I anticipate having that much in a year or less.  Of course, if we get a bear market, I won't have that much.  May have to wait a year or two longer than anticipated.  I'm just trying to plan for the future.  I don't see an easy way to cash out.

How did I get so many?  I make a very good salary, save every penny, and go "all-in" on investments when I believe there's good value.   I did that with BTCs.

Believe it or not, I've lost a lot more in bitcoins than I actually own.
