I don't really want to click on the link. But I do know what I would do if BTC hits $1,000,000. I would buy a house, and then I would buy back BTC when it dumps.
That means you are holding good amount of bitcoin as houses are costly in U.S. But most of the members here might be holding only in fractions and they will be tempted to sell at earlier growth itself because no one has the patience to hold till $1000000. Also, I feel that there will be multiple cycles before that happens consisting of current bull run being followed by bear market and then again a bull run. Bear market can run as long as 2-3 years also and thus to reach to $1000000 mark, we might have to wait quite a bit.
