Not easy to make people buy more Bitcoin nowadays, they want to see regulation from Bitcoin and become securing assets for long term investment without break rule from their country leaving.
I think some of your assumptions are correct, but I completely disagree that regulation will prevent investors from investing their money in bitcoin. Most countries' regulations for bitcoin do not prohibit bitcoin as an investment asset, but it only prohibit using it as currency. Several countries are starting to revise their rules and will adopt bitcoin as a means of payment, so it will support more market demand as well.
Bitcoin is a safe investment asset regardless of state regulations that prohibit it as a currency, that is the reality. The fact is, demand for bitcoin due to its widespread publicity will only make its price higher year after year, it will only be stronger in the future.
