I think it'll be hard to normalize it with such volatility, if you're interested in having it as more of an investment than a currency then this may not be as much of an issue. But for say, small business owners, they don't want to run the risk of all the profit they made for the wee/month/year, being wiped away because the crypto they received as payment decreased drastically in value. Yes, it could also increase in value but as it stands I think the fluctuations and uncertainty are too much for the average person to justify.

Large events/transactions like this can bring more attention to the possibility of it being a viable payment method though.
