You can say whatever you like, and some people are going to continue to use the word halvening or halfining or whatever other variation that they would like...
With a new and paradigm-shifting technology such as bitcoin, there are likely going to be a few new words that come out of the mix (including the fact that there are actual financial and informational battles going on), and/or even variations of old words might be used from time to time to express ideas, and sometimes there might not be a goal to actually want to use a "proper"... .. and maybe even moreso NOT to use any proper word if some people are telling you which word that you are supposed to use.. .. so go ahead, use whatever word that you like.
There will be many variants from an original term and I think of two cases with different usability purposes for people who create or use a variant term.
If a new variant term does not bring any harmful in finance, like halving and halvening, halfining, 1/2 ing, it is nothing to worry. In my imagination, nothing can harm financially by using those terms.
A second case is more serious, as it can be used to scam intentionally such as Bitcoin units. Scammers can use a term bit to scam people and say like I sell you 1 bit at x price, the victim thinks he will get 1 bitcoin at x price. At the end, bit is not bitcoin and it is an unit of bitcoin and very smaller than 1
BTC.
bit is micro-bitcoin (μBTC) which equals to 0.000001
BTC[1]
https://en.bitcoin.it/wiki/Units#cite_note-3You might be correct that the topics might be considered to be related, but I have my doubt that mere disagreements regarding clarifying what unit that you are dealing with would rise to the level of deception, absent some other facts that help to establish that deception had been taking place.
In some sense, I personally get confused by a variety of the intermediate kinds of descriptions that are used to describe units of a bitcoin, and accordingly, I personally tend to gravitate towards referring either to bitcoin or to satoshis.... and of course, it can become a bit confusing to figure out if someone might be using some other kind of unit, and surely people have troubles thinking in terms of factions of a bitcoin.. but they also might have to get used to talking about satoshis as well.. and a lot of the clarification or perhaps the becoming easy of thinking about bitcoin (and it's various possible units will continue to become more comfortable the more and more that we get used to transacting and/or communicating in bitcoin whether it is bitcoin, satoshis or some other way of speaking about bitcoin units..
I suppose I am taking a position that is more descriptive rather than prescriptive in regards to the topic, so in other words I don't give too many shits, don't necessarily want to assert (or impose) my own views, and I am more than willing to see if Schelling points might start to evolve around having certain preferences over certain kinds of unit descriptions as compared with others, and currently it seems that the so far most Schelling points are seeming to formulate around bitcoin and satoshis.
