A lot would have to change to make Bitcoin a valid form of a digital payment system again and the community and devs maintaining Bitcoin seem to be wanting to go down the road of making it a store of value as opposed to a form of payment, not was Satoshi originally envisioned and not sustainable in my honest opinion.
I agree with this statement. Bitcoin has a lot of things to do and to catch up for it to become even at par with the modern ways of sending money anywhere. However, it does not mean that Bitcoin generally is getting to be worthless. While we have to accept that as of now it has had deviated from the most original vision of its founder, we have to understand the way things are and the challenges that it has gone through. Certainly, the journey of Bitcoin has not ended here and I would say that from the world perspective it has just even started. Bitcoin has become popular maybe for just one side of it and that is for speculative purposes and I see nothing really wrong with that because this is an asset albeit in digital form and therefore can be traded just like any other commodities. The main challenge right now is on the currency side and though things are slow I am still in a big faith that ultimately Bitcoin will be a big winner on this aspect, though I don't expect for it to become the prime or the foremost global currency as being the best alternative can be enough.
