Well, if all of those that you have mentioned really becomes true having the problem for fees and delayed transactions happen within this year, then I think that the thing "more and more people involved" will shortly follow. Now, if it really does happen, I am looking at a value of over half a million in US dollars for a single bitcoin alone. Just think about it, bitcoins without issues and countless people getting into it and using it while others are holding, making the demand off the charts. Not to mention the amount of limited coins being used or circulated getting smaller everyday, it will absolutely be a path to the moon!
