I was an early user of Keybase, and at one point they started promoting this crypto currency, including giving away some starting capital. I understand it as a serious project for payments, rather than a cash grab for early adopters. After years of stable value (not even following inflation) it recently shot up in value on trading markets (Trump effect?). However it now seems to be going back down again.

What are your thoughts on this specific currency. Is it worth "betting on" (not specifically trading, but buying as a well functioning payment resource)?
