People in America could be approached by the IRS or others if they sold Bitcoin to dollars, if they bought a bunch of houses with those dollars. I did buy a plane ticket using Bitcoin in 2017 but the website I used probably took some of the Bitcoin to pay for their service and the rest of the Bitcoin amount was probably exchanged for digital dollars meaning the airlines themselves probably didn't take the Bitcoin directly. Some coffee shops in Vietnam said they were accepting Bitcoin but I decided not to buy any coffee with Bitcoin.
Someday, I hope airlines, real estate agents and others eventually do in fact accept Bitcoin directly if they aren't already. But until then, people should buy Bitcoin and hold onto it for many years or many decades, for as long as it takes kind of thing, people got to think long-term and be super crazy patient with investments and everything, especially in this transitional time in human world history which is going crazy right now like never before.
I'm against the IRS but I'm not going to go out of my way to try to get their attention to like sue me, arrest me, fine me, or whatever. My dream would be to someday wake up and find out the IRS was ended. I say as bad as Steem and Hive whales have been, some of the worse whales are in fact the Internal Revenue System or Service (IRS). People probably should NOT spend too much Bitcoin until maybe many years from now depending on what ends up happening these next few years in the 2020s in world history.
