50k-100k is a better exit point
When your grandma and neighbors are buying bitcoin you should exit.
When bitcoin is going up 1000-2000 a day then get ready to exit the train.
We have short term and long term traders, for a short term trader, the $1k is really a good exit point, the only disadvantage of that is that they may find it difficult to enter the market easily if the price does not drop below that $12k again, while for a long term investor, that $100k would really be a very good exit point for the because that is where I believe bitcoin is going to in future.
You are right, we will still have some people that would be buying the little they can buy then which will keep the market active, and that would be good point to exit temporarily and wait for the major dumping for us to rebuy at another low price. I am optimistic that within the next 10 years, the price of bitcoin may really peak at that, so that shows how long we have to be patient for.
