Even though Envion is in our Master Portfolio (an aggressive one aimed at aggressive investors), we don't think calling it a "gamble" is the correct way to put.
Not everything is a "gamble", perhaps you meant "risk"? Gambling means you're taking a chance on something without any indication whatsoever of what the turn out COULD be. A risk is taking a chance on something with indications being provided for both positive and negative outcomes!
We don't think anyone should ever "gamble" with cryptocurrencies, but rather take well calculated "risks"!
