Do people still take profits this days, I don't think so and for that we shouldn't be so moved by the temporary market reactions in whatever direction since in most cases it will just be for sometimes before we witness another price record, so let say I took profits when Bitcoin did the 100k all time high, by now I will be regretting my actions and be saying hard I known I could have waited longer for more profits, so for that we should come to a point where all time high price don't move us so much, to the point of taking action by selling our Bitcoin or other assets.
People that sold Bitcoin at $100,000 don't have to be regretting as the price is now above $100,000. What matters is if they made profit when they were selling as with profits, you didn't lose and don't have to bother about how far the market is getting to go. Being an investor, you should always be following your investment plans and not get easily deceive into holding more than you wanted to or sell before the price gets to your target. You can only do this on some special occasions when you have no choice but to go ahead with selling or holding. Bitcoin is still going to fall below $100,000 again therefore if you have sold at that price, just wait for the market to fall down and buy again while keeping your capital secured.
