But what do you do if bitcoin’s price falls to $8,000? You’ll probably say, “No big deal, I believe in cryptocurrencies.” What if it then goes to $5,000? More than half of your hard-earned money is gone. Do you buy more? Trust me, at that point in time the celebratory articles you are reading today will have vanished. The awesome stories of a plumber becoming an overnight millionaire with the help of bitcoin will not be gracing social media. The peer pressure to own bitcoin will be gone, too.
