Governments of many countries are practically declaring war on cryptocurrencies.
Why is that?
The word war is inappropriate to used maybe they are not interested to this. Maybe they don't have any knowledge about it and they feel unsecured because of the hackers and scammers.
I do not agree with you, because the attitudes of many governments have been openly hostile against cryptocurrencies, and there have even been express prohibitions and harsh punishments against those who dare to trade, develop or simply possess crypto-currencies, and this can be called "war".
But fortunately this has only happened in a few countries that have been unable to react adequately to the technological advances of our times, because it seems that the global trend is toward greater openness, as the countries that make up the European Union at the meeting in the middle of this year.
