I don't even have a plan to get out of crypto and I wouldn't mind if the bull run ends.
When I need the coins, that's the point I sell it to my local currency.
It might be true that bull run might end one day but it will surely be back after bear's table is done.
There isn't ceiling in the price, think about that OP.
at least you have to secure your capital first when it feels like it's enough because it's very important to keep your funds safe. Bitcoin ATH that continues to be printed will experience a saturation point where there will be a decline in price or a correction that will make people panic.
There is no need to do an exit strategy, but safeguarding the initial capital will be very important to keep trading going.
