I think the issue is because some persons just make posts in order to raise post counts. Maybe there should be a better moderation regarding this.

I am not too sure of Facebook's intention regarding cryptos whether they will launch their own coin or not. But one thing I am quite sure of is that Twitter too will make a u-turn regarding its stand on cryptos and would support it as well.

The fact that Bitcoin came to limelight before others is a very big factor. It will in a very long time to come remain the most relevant digital currency.

I somehow share this optimism though. But do you really think banks can disappear completely in future? You really need to think about this.

Tokens to my understanding are cryptocurrencies which are based on the blockchain of other altcoins other than Bitcoin.
