In my view, the only thing that can drive crypto adoption is (1) bitcoins or other cryptocurrencies serving as an escape valve for people who are in uncertain monetary regimes (and willing to stomach Bitcoin’s volatility), e.g. Venezuela, Iran, etc., (2) people buying into the idea that Bitcoin is effectively a call option on becoming a future store-of-value, or (3) people buying the idea that Ethereum, Dfinity, Tezos, and other crypto-networks represent a radical shift in the way computing works (“Web 3.0”) ahead of what will likely be a multi-year validation process. There may be others, but those three things represent to me the majority of factors that could “drive crypto adoption in the short-term.”
