From my perspective it's obvious that in next ten (10) years bitcoin will be centralised and it can be use for exchange of product's in all ramifications and it will dominate any other currencies across the world.
You're probably mixing up the "centralised" word with something else here. If Bitcoin gets centralized in 10 years, or whenever in the future, Bitcoin would be pointless just like the hundreds and thousands of altcoins out there.
Indeed, the OP might have some misconception or misunderstanding with the word
centralized as he thinks that applying it to Bitcoin would be a good thing nor would help any economy if ever his visions would have happen. Yet the funny argument here is that would it be possible to make the vast network of decentralized Bitcoin be
centralized? I don't think it is possible as it requires huge effort and time just to restart a system that has been running on cloud for almost a decade.
With regards to the OP, those what you've called
visions is already possible, as some (actually, most) companies, dealings, and purchases already are accepting cryptocurrency and it is so common for all the visions you've suggested. Actually, it is already Bitcoin Vision 2020. lol
