Let's see...
The BTC bitcoin fee to get a transaction to happen in an hour is currently $13.86
(have to say "BTC" because there are multiple "bitcoins")
The BTC transaction backlog is huge
The BTC bitcoin developers are fighting and fragmenting
BTC mining is centralized with a tiny number of Chinese miners having the majority of hashing power (and thus control over what transactions happen)
BTC money is flowing into BCH because.. just because.
But nobody takes BCH as payment showing that whether a "coin" is used for payment or not doesn't matter (see Ethereum). This also shows whether a "coin" is used to actually buy things doesn't matter at all.
The number of bitcoins is essentially unlimited because ever time there is a fork, the number doubles. It is clear there will be no "official" bitcoin as everyone jumps ship to whatever they feel like.
Other than that...
Some very good points, one might be up for debate though: "nobody takes BCH as payment"
Really nobody? Certain sites I know started to offer more options than just BTC, for instance Dash and also BCH.
Would be interesting to see some actual numbers on this, like top 5 crypto coins offered as payment options currently.
