Sell it and forget about it.
Said the sore loser
If the price falls just keep calm.Don't sell anything because you didn't lose anything until you sell bitcoins.If you can buy more and more bitcoins because the basic law to make money is buy low and sell high.
Thing is that there is a lot of dumb and new money coming in. All these new people have zero experience and knowledge of how investments work. So panic sell will just increase over time.
It's not a problem. You've just explained the situation to yourself. If the new inexperienced panickers are coming in then they will buy and sell, but never reach the real lows, like $3000 we had last year. If the laws of supply and demand are in place those new people will never be the reason the coin falls permanently. They will sell whatever they bought and that's it.
