Re: Cryptocurrency usage will boost economy or make it worst ?
What if all those big corporates and businesses starts using crypto as a mode of payment just to avoid tax which will cause a direct loss to the government which uses tax for the betterment of the country. This might not affect corrupt countries as it doesn't matter because tax money goes to politician's coffers but what about developed nations?
Is that even possible ? If that's possible the government will ban cryptocurrencies for good and anyone caught using crypto assets will serve serious punishments, especially companies that are caught using it will face serious issues. So, I don't think any of them would like to try such a thing. But, I know for sure that if any company is making use of cryptocurrency they are still going to be paying tax while they are making use of it.Both, some people gain millions from BTC and other Crypto investments, and some of people lost everything they had on the ICO bubble. So IMO it can make economy better and worse 
I don't know if it does have any impact on our economy. Maybe when in a particular country and there are lots of investors holding crypto assets and making profits, if they withdraw it to their country bank it might in some way boost the economy. I don't know if this is right or not.
