So, the question is really about adoption. How do we expect cryptocurrencies to be adopted as valid payment methods when everyone is really using them as investment stocks? Will we only see proper adoption once the current greed and "quick buck" mentality subsides?
The price of bitcoin has a seasonal tendency to peak at the end of each year during black friday on expanded transactional volume and higher demand when peak christmas shopping is occurring. This suggests that not only does bitcoin (and other crypto currencies) function as a store of value, it also has a secondary role as a true currency which people utilize to get their christmas shopping done.
The concept of bitcoin needing to utilize a heavy volume transactional model where people use it constantly for anything and everything never had any real evidence to support it, in my opinion.
It is often faster, more efficient and cheaper in network fees for people to utilize altcoins for a transaction heavy role. Bitcoin can be relegated to a role which emphasizes store-of-value and let altcoins be utilized for coffee buying and whatever other buying/selling is necessary. That arrangement makes sense. It appears to be a natural progression we may see in the future.
