for people telling others not to sell, you're fooling yourselves. Seriously. I wrote a comment about 2 or 3 days ago when bitcoin was worth close to mid $7k then it went back to $8k about cutting losses. Look, you can sell your bitcoin, sell it. If it dips lower, buy more of it at a lower price. If you bought a house at $300k and houses in your neighborhood are now people ar ebuying houses that look like yours in your neighborhood for $50k, will you continue to pay that $300k mortgage? only a stupid person will.
Here's the real truth. You've lost loads of money and if you bought bitcoin at 19k, you've lost over 70% of your money and you own less assets of bitcoin. You could have more bitcoin by selling now and waiting for it to go lower. When will long term investors start to see that they lose so so much money on a virtual asset that's intangible? A word is enough for the wise. Sell it now, wait for the price to stabilize then re-enter the market. For those who don't own bitcoin, maybe for you this is the perfect opportunity to buy. Then buy it, do it if that price is right for you. My only caution is for people who bought it at an higher price over 13k and are still waiting for it to go back to that level. Look, it probably will but guess what before it does, you could own two bitcoins before that time since the price keeps falling.
One thing to also remember, with the price of bitcoin falling, regulators will continue to now say that it was a bubble after all. They will double down on efforts to limit crypto trading to limit the risks it poses to people. Also, those with crytpo assets will sell more cryptos around this time. Valentine day is near and will need cash for purchases. There's more to come in price dip, this is not the end of it. You can hold onto it forever till it becomes $500 in your hands though and keep dreaming of that opportunity you had to sell it at $6k.
