Obviously blockchain Technology needs everyone. Becouse Blockchain technology is greatest and latest technology in tha world. It is blessing for Modern economy.
Technology is the most important factors which are linked with other sectors which have a great vision to all other sectors and it is going to be beneficial. That's why many companies are showing a lot of interest towards the blockchain because it's ecosystem will work efficiently in all the sectors perfectly.
But why there are some countries who are banning crypto which is having blockchain technology and one of that is bitcoin, I think probably they were afraid of having transparency which is only blockchain technology have, of course, the corruption was still there they will track if everyone using blockchain. Therefore, I conclude that we really need a blockchain technology which gives us an easier life and easily across wherever sector you are.
