No. Many, if not most, register domains with the hope that someone else sees value in them and pull out their wallets. We're talking about hand regs still.
No. I am stating that investing happens when you see a clear value in a domain and are willing to hang on to it year after year when a fire sale does not occur.
Yep. With domains, like real estate, you have number of options to profit from them. Not just outright sale. When I write investment, I mean profit, not losses. So people who bought into stocks, crypto, etc, and then lost on those then it wasn't investment, it was junk. They speculated or rolled the dice just like hand reg'ing. Investment makes itself clear as valuation or returns increase over time. In the case of stocks or crypto, you can pull out early and minimize losses but then you don't see value in hanging on to them. Or, if you have understanding of the markets and can see the value, you may decide to storm the weather and hang on.
The bottom line is you have to have an understanding of the value of a domain. You have to see the way it can increase profit or material assets in a real world setting. You can play investing like you play slots at a Vegas casino but is that really investing?
