Honestly anyone investing in bitcoin should know this and also separate their money into different category.
Managing to survive in the market volatility is a lot easier when you got money stashed for your emergency situation, so you won't be those kind of people who panic sell and become a paper hand.
This is exactly what I did when there were many dips before the big rally comes in, since I stashed money for emergency fund I can just ignore the dip or buy it even, and then move on.
As a result, I still hold my BTC all the way until now and will still be holding it for years.
Thats how it should be but tons of people do failed on doing so just because they've been that expecting too much about into their Bitcoin or crypto investment on which they've been even thinking that they can assure out profits at the time that they would be investing into it on which this is that a very wrong mentality. There are those who've been that too optimistic towards it on which it isnt bad but just like been mentioned or said that you should be allocating different funding when it comes to investing and never ever forget your emergency funds as well on which this isnt just that make use on emergencies literally but also you can make use of it when you are tending or trying out to make out some investment or business on which at the time that you would be needing up these funds then you wont be having any problems with this. There are just that those times that you do become that taking up such step just because you've been that thinking that this would be your last shot for you to make money or having some profits. On the time that the market do make out some correction or plunges then you would be that easily get panicked and this is why its recommended that you do know on what you are that doing at least so you wont be expecting up that much and easiyl moves on. It all matters about on how you would be having that management.
