Speaking of 2013, that is when the Winklevoss twins plunked $11 million on BTC. Now, 4 years later, those BTCs are "worth" over $1 billion. There is nothing normal, credible or justifiable about this stratospheric rise. At least not from where I'm standing. Sure, I'm pissed off I didn't get in on the ground floor, but those feelings don't justify its current "value." You obviously did well, and damn good for you. And you may continue to do even better. I'll watch from a distance.
Prices don't need to be "credible" or "justifiable." This is a key lesson in trading. Some never learn it.
I stood where you were standing, fwiw. I paid $550 (using a midpoint value) per 1 bitcoin knowing 3 years before I could have had 10,000 bitcoins in exchange for buying someone a couple of pizzas. [On a related note, there was someone selling 10's of thousands of bitcoins for a couple of thousand dollars back then, too]. https://bitcointalk.org/index.php?topic=137.0 .

The biggest problem of the unreality of the price raise is: The bigger the price the less usable is bitcoin because fees are simply prohibitive and the network is slow. In short, it is going to shit as a currency. BCH is the true contender and it will take probably less than a year before the market completely recognize this, switching the prices between BTC and BCH. Obligatory McAffe quote:
You're right, they don't. And I can stick to the knitting that I know while you talk a good game. I did not have the forethought to get in while the getting was cheap (although maybe even then it didn't appear cheap at the time; I don't know because I wasn't interested). But the idea of getting in at these prices after such an unprecedented runup into an unregulated market that can be easily manipulated and that appears very opaque to someone with my limited computer background is not even a consideration. On the plus side, I won't get poorer as you get richer.
