Bitcoin needs to work as a currency that's what we really need not many people are going to put their money bitcoin if it is just a high risk investment, after all how many people are investing in those kind of products not many I suppose, but everyone needs to use currency from the richest man in the world to the poorest so until bitcoin is able to satisfy that condition then we cannot get mass adoption.
Bitcoin or any other crypto currencies that exists currently is not suitable for being a currency cause of the volatility in the price of the coins. The only time when a crypto will act as a currency is when it will be centralized and made by the government. Government wont allow some decentralized crypto to be used as a currency which is volatile in market and can disturb the whole economic of the country and also the international trade markets.
Cryptos will only be used as an asset and nothing much, the point is about mass adoption, which is also possible even if cryptos are considered as an asset. Gold is an asset, but it has mass adoption. In the same manner crypto will have too.
