It would be great to see it adopted in Britain as they are very influential in financial markets. If adopted in London then the rest of the world will follow, more crypto companies are establishing themselves in the UK such as farmatrust which is a well respected ICO. This will change the sentiment towards crypto for widespread adoption.
First it would be great to see a real proof of the survey because I don't believe the numbers are correct.
Also London isn't that important, especially now when they're leaving the EU and will have to pay them to do it. Short term it's going to hurt them but long term they will be doing better than the rest of the union. But now we also have this dispute with Russia... Who knows., maybe we'll have a war in Europe soon.
