10+ years is considerably long and we're not sure of the next minute. Holding for such long years and we're not able to enjoy the outcome is really bad. The right choice is to move along with the market. Just fix the years of holding, in between based on the market movement book the profit and find the opportunity to reinvest. This would be better than just holding for 10+ years.
Exactly my point, knowing the right timing has its advantage because no one can tell what the price of Bitcoin will be in the next 10 years, it is possible that Bitcoin price at that time may be lower than now even though the chances are slim due to multiple bitcoin halving that will happen between that time space that could possibly trigger the price of Bitcoin to rise but again we are not certain when that rise will happen that means there is also a possibility for a drop too.
But if one holds for a sufficient time not too long let's say considerably around 5 years it will become easier and better to cut profits along that line because the possibility that the price will make an all-time high between that time is high, so waiting won't become a death trap for Bitcoin holders who may discover that the price in 10 years is way below the current price.
