We cannot say that the BTC price witll certainy go up in the future, even if it seems that it has a strong investment thesis. We can say that for sure if we do not invest with leverage, then the most that we will lose by investing in bitcoin is 100%, but we have decently good chances of being able to put ourselves in a better position by investing into bitcoin rather than not investing into bitcoin as long as we figure out some way to balance that we do not overly invest into bitcoin
That's true there is no guarantees that Bitcoin price will keep on increasing in the future. But in this past years Bitcoin as proven it's self worthy of being one of the great investment so far , and Bitcoin still possess same energy ( having a nice potential). Well we can't actually tell the future which is very obvious. But still we just need to be in a better position in our Bitcoin accumulation. That's why is always advisable to invest with money you can stay without using for long. Because one thing for sure Bitcoin is here to stay so is better to be among those with some nice quantities than having none.
Basically those are the investors who usually do the DCA in bitcoin to accumulate the bitcoin throughout the bear market. Those are the people who will then sell in the bull market and gain maximum return on Investments. I will not compare them with the traders who have different mind set and who will usually buy and sell multiple times to gain profits
Well accumulating during the bear market is pretty nice too , but when it comes to withdrawing or taken profit from your investment it doesn't actually depends one accumulating during the bear market. Because there are some folks at there that literally accumulate some Bitcoin during the bear market but haven't gotten far with their investment due to some reasons. So those that are fit to take profit are those who have gotten to the point of having enough Bitcoin stashed in their portfolio. So all that truly matters is the number of Bitcoin stashed one possess.
