$1 billion? That's an awfully high cut off since there aren't any cryptocurrencies in general that meet that requirement besides bitcoin.

I could have set the bar at $150M with the same result. For a currency market cap, $1B is super tiny.

I noticed how you left out crypto in "currency market cap" and just threw all currencies, crypto or not, in one basket.

Cryptocurrency is in its infancy. Proof of stake has had a lot of success and a lot of new currencies have and continue to adopt it.

What more evidence could you realistically expect to show the viability of proof of stake?
