Imo, bitcoin adoption is more related to how the people, government or even businesses sees Bitcoin, and how they choose to use it. Holding is a form of bitcoin adoption... Accepting and sending, In the form of a payment system is also another form of adoption. And mind you, whether you choose to trade for a short term or long term, you are still an adopter. Let's not forget that it has always been about a peer-2-peer electronic cash system.
So what you’re saying in other words is that, folks who decide to buy bitcoin now, wait a few days/weeks/months, for the price to go up, and when price surges, boom they sell off, that even these folks are also called investors and HODLers just because they bought bitcoin, held it for some time and sold it? Because this concept basically sounds like actual long term holders, just a difference of the time horizon.
You're actually replying to something entirely different. The discussion is about the things that brings about Bitcoin adoption. The OP argued that holding, or buying and selling is not enough, and went on to say that understanding certain things are far more reasonable points to classify adoption. And if you can take a moment to go through my own post I quoted above, I shared my own opinion on what I think adoption truly means. It has nothing to do with if someone who sells or buy is called an Investor or not.
And, I just read through what I wrote, but still couldn't figure out where I wrote what you understood. My own definition of adoption still boils down to usage, and Bitcoin usage differs for everyone. Holding is a form of adoption like I already pointed out, same thing for those who buy and sell, or those who trade. It has nothing to do with who's an Investor or not.
The fact that two concepts looks, feels or sounds alike doesn’t necessarily mean they’re the same thing mate, and drawing a distinct line between two familiar but different concepts makes you logical. Anyone can argue that short term traders are actually investors or HODLers, just as anyone can argue that Bitcoin users are same with Bitcoin adopters, but only critical thinkers would be able to look beyond the similarities and realize there’s actually a difference between the both concepts.
Like I said, the discussion is about bitcoin adoption. Be it an hodler or an Investor, or a trader
(I'm still yet to figure out what you're trying to point out), it doesn't really matter because they all use Bitcoin in different ways, which makes them all adopters of Bitcoin. The key word here is 'usage'.
