Before I type what I am going to type I'd just like to mention I hodl and don't sell and I am pretty stubborn with this. I have no desire to see bitcoin drop in price at all and that won't benefit me in the slightest.
On this note I'd like to say when people talk about $10k, $100k per coin etc I worry and expect a big correction. I am sorry for saying this but we all know it can happen at anytime and it's more than likely coming soon when we least expect it.
Anyway, please continue upwards bitcoin and keep us all happy little hodlers! This is the most fun I've had in nearly 4 years being involved in this.
You gotta sell at some point, no?
Whether you are wealthy in cash or bitcoin or gold, you have to sell some in order to get some of the pleasure of it, right?
Another option is to sell some of the appreciation, rather than the principle, but if you count your principle in terms of bitcoin, then of course your supply will diminish a little bit when you sell it .. at some point.
Also, there is some value in diversifying and reallocating from time to time... and people will chose at different points when to reallocate. Everyone should consider triggering mechanisms for such reallocation - even if it happens to be what I would consider to be a bit high (such as 10x appreciation). I personally think that you should reallocate on quite smaller increments.
