So it's cheaper to use Paypal ?
So now it's back to being cheaper than Paypal, but yeah, there was a time when there were $100+ transaction fees. And it may hit that again if transaction numbers go up enough to fill up blocks with the new implementation.
There are any number of other popular coins out there that have the same or better liquidity as BTC that charge tiny fractions of the fees. And also settle in seconds.
You're saying Bitcoin like BTC, but the parent commenter was probably referring to the giant ecosystem of coins, that happens to include BTC, but also many other much faster and cheaper options, that are used to globally remit payments every day.
What it's replacing, by the way, Western Union, Wise and the like, is also pretty unblockable and unrefundable.
And yeah, the thing is, payment systems that work approximately as well as BTC exist without being cryptocurrency and using up so much electricity on mining. The main difference is that they don't operate in some areas where BTC still can (like evading sanctions, like this), and the speculative nature of BTC (which is actually a net negative on using it as a cash).
