and basically all 2019 almost all coins were in red zone..
so you are really lucky person and I'm glad for you that you made solid profit from your sale..
as for me, I do not have any deposits, but some good trades also brought me some cash..
You are 100% wrong! A lot of my friends bought in January 2019 at $3000+ and they sold at a good profit in June 2019 and also recently when the price went to $8000+
The common mistake people make, is for people to buy at a all-time-high and then not to keep on buying when the price drop. Yes, you lose money when you sell those coins that you bought at the all-time-high, if the price do not recover or exceed the buy in price, but you win, when you buy again when the price is very low and you sell at a profit.
We always say, "Buy the Dip" but a lot of people are greedy and they dive in when the price is at a all-time-high.
from those people that i have seen, their problem has nothing to do with greed but it is all about their lack of experience so they don't know what to do and end up with tremendous amount of fear specially when they listen to FUD.
for instance take your example here. these people wanted to buy bitcoin and saw the price drop and it being a great opportunity (being at $3k while it was $20k not so long ago) but they didn't buy because they feared it might never go back up. why? because some random person on the internet spread this FUD! so they didn't buy.
Yes, and you should also not forget that the person already feel like he/she burnt their fingers with their Bitcoin investment, so they will be hesitant to drop more money into something and potentially lose more money, if it goes to zero.
So it is easy to stand on the outside and to criticize them, because most of us would have reacted in the same way. It takes a lot of courage to get back onto a horse, once you have fallen off. The people who had the courage to do this at $3000 was very well rewarded for taking that risk.
