My first thought on this is what regulatory body will be in charge of the tax levied on crypto? What will the proceeded realized from the taxation be use for?
There should also be a particular means for the calculation on the tax that will be levied on individual. The rate of income of individual steemians are different. Some earns cents will others earn dollars in large amount. Tax should also be considered based on the movement of the crypto market.
As per building of an app that will help in regulation levied tax, that is a very welcome idea. This app should be able to show how the amount deducted are being calculated, the app should be able to give an up to date information on the current market happening in the crypto world.
