Bitcoin is fast becoming a universally accepted cryptocurrency and truly so, it has established itself as "somewhat" parent coin to the likes of Etheruem, Litecoin, Dogecoin and many others.
Not sure if this is true, not all countries are willing to accept bitcoin as crypto, there are a lot of them who ban it totally. It's more of a prime mover though, like Ethereum.
Few years ago, some many predicted bitcoin was going to fade away like some other cryptocurrencies but instead of falling off bitcoin has grow stronger and have been widely accepted for transactions.
The biggest breakthrough for bitcoin is seen this year, the coin value has consistently rise and even government of most nations are endorsing and legalising it for transactions.
I think even before the inception of bitcoin, it was supposed to doomed as failure.
But now, look at how big it is, and it can't be stop. People all over the globe wanted to get their hands on it. El Salvador for one has legalised it, but we have to wait till other countries follow suit as well.
