When BTC reaches a new ATH, there's no reason to keep holding, take your profits, and then hold them, you worked hard and your dreams came true, so enjoy them, but keep some money in reserve and wait for another great opportunity to grow your BTC. This is also a great way to increase your BTC.
A great reset can result in 1 BTC if you buy back afterward. People want the bull market moment to last forever, but sadly those moments never last, so if you know how to take advantage of it, it's a good way to get your retirement plan working at a greater speed.
