Maybe they will but I'm not sure if some of these investors still manage to hold until now or if they sell it before it hits $50k.
Those who have strong mindsets will still hold and accumulate more but those who are easily affected by the FUDs and rumors, exactly they got in panic and sell their BTC at low prices. We never expect everyone to hold and wait for the new ATH because many investors are weak.
BTC is already $60,798 and being able to survive this to date and purchasing the DCA model is an extraordinary achievement even though it is not yet full. Well, regarding some people who sold their BTC before today's increase, I don't think they are weak in holding their BTC, they just have to sell it urgently for important daily needs.
I will say it wasn't really a good idea selling bitcoin at this point when the price keeps maruding forward and the halving around the corner. Selling your bitcoin yesterday and seeing the price surging ahead is definitely going to have some psychological effect of that person. Bitcoin is heading above the $100k as speculated. If you have been holding bitcoin coin till yesterday or today you can keep holding. That's why it's advisable to always have other source of income Incase of emergency. Bitcoin is the new trend and if you are opportuned to have it, don't lose it cheaply.
