Well it’s never a good idea to sell your entire stack but there are times when taking profit is essential. Altcoins still seem to follow the standard four year Bitcoin cycles which most of us are familiar with. Obviously the answer to your question is to sell when you are in profit. To maximise your profits though you should sell some in halving year and one year post halving, specifically the year post halving so that’s next year.
Interesting strategy! I’m also waiting on some price movements from altcoins I got a few years ago through bounties. Hopefully, they follow the cycle you mentioned. My target is around the presale price or the token’s ATH — or at least close to it. I’ll take partial profits and then go into wait-and-see mode.
I’m really counting on this bull run since I’ve been holding those altcoins for quite a while now.
