I think the article is quite harsh, whatever the opposite of rose tinted spectacles are is what the author is wearing imo, but yes crypto would gain better traction if it offered the option to work with USD or EUR as well as an unstable backing currency like Bitcoin.

Luckily BitUSD and BitEUR already exist - https://bitcointalk.org/index.php?topic=922252.msg10128457#msg10128457

You can already hedge in BitUSD/EUR/Gold/Silver in a few seconds inside some of these wallets with no centralized counterparty risk. So you can not be exposed to the crypto downturn at all & still stay in crypto if you like.
