Ya... And the internet is used for pirating media, porn, wasting time browsing, gaming and the other millions of "useless" things that it's associated with. The amount of sheer time wasted on the internet is incredible, let alone all the filthy illegal things that are happening on it.
Guess we can throw the internet into the trash bin too.
I remember the mantra well. I remember the backwards messages in rock music were blamed for brainwashing kids. They would slow a record down and play it backwards and come up with words from the noise that matched their fear message.
So does any traditional government issued currency, credit cards and banking loans and that doesn't make them useless to me.
Would I work for a crypto startup or as a crypto developer in the US if I'm not a citizen? No
Does crypto work as advertised? Yes
Social wellfare, a 401k, etc... are also "get in first get more money out if you get in late" schemes. A lot of people already cashed out their crypto to tangible assets and are set for life. A lot of other people have our pools as a risky investment and every once in a while rabalance and it puts food on the table. It's full of people with bad intentions but open your eyes, so is the world, those people are also doing pump and dumps and pyramid schemes with fiat and the stock market and putting hits on drug dealers over snail mail or dead-drops.
