VERY GOOD ADVICE !!!!
You should trade BitCoin based on facts, not emotions. The biggest problem here is that people are so in love with the IDEA of BitCoin, that they will likely HODL onto their BitCoins when the financial indicators say it is time to sell
Hard Facts
It is usual for people to react according to emotions - that's what we got them for - that's a hard fact.
If someone is fascinated by something and loves it, just like Bitcoin lovers, why would they sell it if they believe that cryptocurrencies are the future?!
I'm afraid your hard facts have nothing to do with reality and the freedom of choice for every human.
When it comes to the fact that selling during panic is not a good decision, it is obvious and if we do not have investment priorities set (before we invest), we should not invest on high risk market.
