I'm sure the number one thing bit coin is used for is trading but that wasn't its original use and seeing how it still has value and exists a decade later it has utility. Officially what else is it used for?
You have been a member of the forum since 2017, you can at least write the name of something correctly before asking a question, which by the way has hundreds of very extensive answers if you use search engines. ETFbitcoin he briefly told you what you can do with BTC, but it again depends on your location - in some countries you can do more, in some the offer is very weak or non-existent.
I thought BTC was going to replace western union by now and be used by official brick and motor businesses. I guess thats the point of stable coins, Why doesnt BTC have a stable coin backed up by BTC; kind of like how they back up mortgages. I wish I could remember my series seven better I could think up more use cases for BTC.
You live in the illusion that something created over the centuries can be replaced in just 10+ years, just as the illusion is that Bitcoin is something that must replace the existing financial system or various services that exist when it comes to money transfers. Bitcoin was created as an alternative, and it's not realistic that it will wipe out banks, fiat or WU in the near future - because let's not lie to each other, BTC is not something the average Joe can understand so easily, much less something he wants to use at all.
Most people in the world are extremely submissive and serve their masters in the system they have built for them, and those 1% or maybe even 2% of the world's population who use BTC are exceptions - be happy if you are one of them.
