How much is the taxation on Bitcoins in your country ? Is it reasonable or government is just trying to make profit out of it ?
it depends on the country and what they are taxing, you can't tax bitcoin. but you can tax miners, traders, merchants,... and it is all reasonable in my opinion but taxing people for using bitcoin as a currency is not since it would be like taxing them if they used another fiat instead of the local fiat currency. not to mention that some developed countries are already taking this route like Japan.
if you compare each case with similar real world cases you can see that for example a miner is earning money like any other business, like a gold miner and has to be taxed, a bitcoin trader is also making money like any other trader such as a stock trader so similarly they have to be taxed, same with merchants.
