That's a very good question, one that I don't have an answer to. "A very solid choice" was a very poor choice of phrasing. I was intending to generalize the reasoning behind the recent surges in value and popularity.
My statement was more intended to be a critique on the current perception to the layman. I believe bitcoin and crypto as a whole should be looked on as a currency, rather than a get-quick-rich investment that absolutely anyone with a spare penny can leverage for their own profit.
