Are there other strategies for profit taking?
I think it is the common and you've said it about DCAing. This one;
2. DCA out at every milestone of the project.
You sell whenever you are in profit and you just do it every time that you're going to need some money. But apart from that, as long as the price targets are being hit, you'll sell maybe 10% or so depending on how much you need.
Not another strategy but it's very common when someone does this because it's very effective and the rest that you still hold could bring no longer heart feelings when you've taken out already huge profit.
