Everybody is in a different situation. Anybody who bought pre 2017 should probably have taken some pressure off their lives by buying a house or something. Never sell all your bitcoin, hell don’t sell over 50% but it’s a good idea to sell some to make significant positive changes to make your life better.
Can't agree more. We have different status and priorities in life. Hence, the time we plan to cash out varies from one person to another. Depending on the situation you are in, you can either hodl until you can and/or cash out from time to time whenever you feel like it or need it. After all, we should still enjoy the fruit of our patience even just for the little things.
Personally, I prefer to practice delayed gratification so that the reward will be bigger and more satisfying the moment it's already the right and perfect timing. It could be different to you and to others because some might have cash out now because they need to in order to survive or get by.
