I didn't need to sell, and it was mainly for the satisfaction of getting back some of my original investment.
However, I also feel like its broken the "HODL AT ALL COSTS" mindset which I felt was getting a bit unhealthy.
I do feel there are risks with Bitcoin, and I won't drag people down with that here, but I will be diversifying that money into gold and shares, mainly tech shares.
If Bitcoin dips a lot, I will also buy some more Bitcoin though.
Basically, I'm glad I sold some if only to stop feeling like a slave to it (and to test the Coinbase selling functionality which only took seconds for the transaction).
Selling Bitcoin at the $60k means a lot and if you sell it on $30k or on $40k then the price is also good as compared to the previous pump which was a maximum of $20k.
