I don't know about keeping it forever, but for the next cycle, I'm putting together a kitty of about 13% of my holdings to take as profit. I'd based that on Hive reaching 2 USD in which case it would all be tax-free. At 10 USD, I'd see about 30% of it disappear in tax. The remainder would still give me back my original stake and cover the outstanding mortgage. I have thought about putting some of it aside to increase my stake when the cycle dips, but I don't have clear plans yet.
I feel it's pretty important for Hive to have a reasonably sized middle range of stakeholders - Orcas and Dolphins. At 10 USD there would be a very nice (semi-)passive income from HIVE and second-layer tokens as a mid-range stakeholder. Things would change, that's true, but there could also be better opportunities for creative people. I feel the thing there is building your audience, developing the relationships. It has already changed. I used to enjoy sitting down and watching a video from a homesteader who'd just come in from working and was sitting at his kitchen table chatting, just like you were on the other side of the table. I loved the insights into people's lives, the reality like one person tipping back on their chair and then toppling over.
But there you go.
