Crypto is being used worldwide already and some people think it'll be our major currency in the future. I invested a few months ago and i've read articles that say how banks manipulate the people's money which in turn becomes a scam. I never really trusted the government since some politicians usually are in it for the money and power. I fimly believ that the crypto industry will not end and hope that in a few years, it'll be utilized more efficiently towards the betterment of our planet. 
It sure will be utilized more as many ppl already know crypto (at least they will google bitcoin), crypto is the alternative of fiat currency too.Politician will affect monetary policy and central bank print money too, if politician wrong , then country will be big trouble.
Not being negative but I don't think it will be the "major currency". Real talk, not everyone will have access to crypto even in the future. This "Crypto Dream" will not be acheived because we still have many issues about technology all around the world. Plus not everyone can afford one.
Yes it will not be major too and country will not hope its fiat currency become alternative ><Yes crypto dream is difficult because crypto is technology things which not 100% safety and hacker still have chance to hack our coin.
So as personally u need to do safety on your coin too!
actually if u are beginner i will not ask u to buy a lot of crypto too, u can try small one. try how to do transaction, how to trading and maybe how to kept your coin safe too. after u know a lot of things, u can step by step involved in crypto world.
