Due to the fluctuation of Bitcoin price most investors who are holding their Bitcoin are scared of losing their entire Bitcoin because of the frequent changes of Bitcoin price recently, some investors are panic of selling all their Bitcoin because they don't want to lose everything.
So what are your advice to those long-term investors?
Should they sell their Bitcoin or they should keep holding to it despite the unstable state of Bitcoin price recently?
I think you should be more specific instead of just saying 'most investors' because that's not the reality, it is only the investors who lack a proper understanding of this market and Bitcoin in general who would think that their invested funds are at a risk if the price is going down and that they are going to lose everything if the market doesn't stop going lower. An investor who knows everything, has enough knowledge about the market and Bitcoin in particular would know that such things are pretty normal, and that the prices will eventually recover and they are not losing anything.
And, about the most recent drop in the price, it's not that severe, to be honest, and it is caused because of the Binance hack, and I personally think that based on the fact that this was the biggest crypto theft of this industry so far, I think the effect of it on the market was way too lenient, and I was expecting more bleeding, but surprisingly, the market didn't react so negatively about it, and that's great, because it proves that the market is getting mature over time.
Finally, an investor should always remember one thing, a loss is not a loss as long as it is unrealized, and if you turn your unrealized losses into realized losses then that's your fault, because Bitcoin has the potential to turn the tables over time, you just need to have trust on it.
