There are many reasons for this, but basically I see that it is not yet universally accepted because there must still be objections. Just like you see a benefit, but other people don't see it as a benefit, try a product like cannabis, and you'll see ' why?'.
What a comparison.
It is what people see on it and as well as the governments. A lot of governments don't like it but we're here and does like cryptocurrencies because we see the benefits from it.
Maybe, it's not just really for everyone.
