This was true in 2018, but the cryptocurrency world has moved beyond bitcoin being an easy way to make transactions. That was just the beginning and Bitcoin doesn't do a good job compared to the newer Blockchains.

Right now you can buy Bitcoin via bank transfers which the fee for it can be easily low as you as 5 USD depending on the provider, I buy with fee of 0.1% normally. So the transaction fee in the article is not true anymore.

You can also use bitcoin as a collateral for a loan. If you have bitcoin savings and suddenly you need to cash out temporary you can already do that.

And if you look into news you can see banks and trust funds holding bitcoin as an asset.

The cryptocurrency and decentralised market has to grow, it has a lot of problems, but there's a crazy amount of investments on it so problems are being solved and new things come out every week.
