This could make it rather difficult to use Cryptos as a medium of exchange for buying and selling due to the obligation of tracking the tax implications of every transaction.
My exact thoughts are that they want to prevent it being a legally acceptable medium of exchange. Classify it as a property and it's no longer possible to use it as a currency for exchange reasons simply due to the tax implications. Time will tell.
Personally I think most Cryptos will be killed off by the Governments once we have accepted the technology , we will be herded into Government coins sold as safe and employed by the banks as the only medium of exchange.
