If there will be taxes on bitcoin then it is a good sign and development to bitcoin. If taxes were placed to bitcoin this means that the certain state who placed such rules have already accepted bitcoin as a currency. This will provide bitcoin a greater market since the state has recognized it, this will also promote bitcoin usage and increased its users.
As a crypto currency trader and a bitcoin enthusiast i am not a fan of the government imposing rules and regulation and these sort of taxation being imposed on the crypto currency market is just absurd ,we are here for the free market away from the corrupted government and the banking system and now they wanted to exploit this market too.
