I'm agree that will be very hard to become a true holder if we always check our asset's price progression, if we already made profits more than 100% less than a year, it's already super big return in any kind of investment exist, so if we think with logic, we should sell it right at the moment we gained the x2 profits.
But for the people who has the dreams to be rich and don't want miss a chance of being rich, they must be hold it in case of hoping the coins will gain even more.
100% could even be a bit low thinking how bitcoin could do better than that. So, we are talking about by far the best investment aside from a few years, 2018 wasn't but that's about it. When you are making that much money with something, to wonder if you should hold more is a weird thing that I do not really understand very well.
People see this as a scam I believe, there are still some people who think that bitcoin and crypto are scams and they want to make money and get out as quickly as possible. That is not something that I really want to see, it is not really ideal and I would rather have something that is a lot better in the long run, realize that it's legit and it could make a decent money for you if you hold it long enough.
