I still see the transactions made to a gambling account, that is things like funding your gambling account as mini transactions that people are already doing and indoctrinating themselves even without their knowledge into being able to spend bitcoins on other mini transactions when the time comes. Now it may seem that microtransactions with bitcoins were only a thing during the early days of Bitcoin alone, but I feel that we're in a cycle and something that has trended before will also trend again. What I'm saying is this, Bitcoin will be used again for micro transactions as time goes on and as more people get to the knowledge of it and have some Bitcoin in their holding.
Many of the persons who feel that they will not be able to use the bitcoins they have for micro transactions will be pressured into doing so when they find others around them now using Bitcoin actively for micro transactions.
