Firstly; I need to know if its allowed in the united kingdom and about taxes.
I will not advise you to make any crypto establishment in US, you may need to know about the experience in which others are passing through currently concerning their crypto business and establishments over there.
Secondly; I need the best possible links about finding information about tokens and how to go about it
I will advise that you go to altcoins sections to read more on them.
lastly; Just so you know I won't be telling my idea to someone that is just going to run away with my idea, got to earn my trust.
There is nothing new that have not been introduced or done before, but if you got in some new ideas, its better you left them to yourself till you work them out and implement on them.
