I wish I was accumulating Bitcoin for last four years then I would be in much better position. Still I am happy with whatever I have. I do agree that selling at this time is not a good option because one might miss bigger piece of cake coming in next few months.
I told you my situation for which I did that and I am happy that BTC has benefitted me and my family in big way.
This help from BTC has taught me a lesson to keep investing in BTC to improve standard of living.
a bit after the 2017 ath (21k) when btc price had fallen to like 13k usd or so i sold of a good chunk of my stack to augment my retirement plans to the point where i retired years ahead of even my most optimistic estimates.
best decision ever. wife and i are having a blast and no clocks or worries.
only you decide what is best for you and yours.
You are lucky to sell at 13k because AFAIK the price after Dec 2017 ATH went down to 3.5k in Dec 2018.
I fully agree with you that you must have your own strategy with you that tells you whats best for you and your family.
