I don't think that your opinion will apply on every country. I think they will also tax you base on your earnings. For example, here in the Philippines, you get taxed by 12% of your total earnings. And every country has different styles of taxing.

If the government introduced such a tax measure, in the short run it certainly has an impact, but in the long run it may not be certain

i think as long still worth it with the income and the lesson about bitcoin for me i will pay the tax. it is the best way than government block bitcoin in their country, we still can access bitcoin in my country

If the government put tax in btc, some people won't like it and leave the cryptoworld because btc has a high value (completely volatile) it makes higher taxes. But I think when you get or withdraw your money there's still a tax. The one thay you'll pay after the transaction.

I dont know for sure, because right now it has not happened for my country. I think there's going to be a profit and a loss, that's for sure. but if analyzing from what happens it might be good if the state is involved in bitcoin.

The government will make a tax for digital currency, as a good citizen I am ready to be in taxes such as transactions or taxes.

If the government imposes a tax on bitcoin then the profit automatically decreases, but the interest of people to follow the bitcoin will not decrease in my opinion, bitcoin is a job that will not require the labor to work so that people will still be interested to use bitcoin.
I personally feel very grateful if bitcoin can be licensed from the government even though taxing, rather than bitcoin is still illegal, it is better to have permission even though there are taxes used by the government.

If they tax bitcoin, soon enough they have most of coins in their possession.

I agree that the profit will decrease but it'll be more attractive because the government only can put tax on Bitcoin income when and only when they can be able to legalize Bitcoin in their country so when Bitcoin is legalized, it'll be widely used as a local currency so the number of people using Bitcoin will increase and it'll make Bitcoin become more popular and acctractive.
