Also, the more people we have, the harder it will get to get new customers as well. I mean if you have everyone involved already, it would be hard to convince the last people, they waited that long, they may have a solid reason that we can't change. So, the long time we spend with this adoption rate, the harder it gets to convince others and we should be careful about it.
I personally do agree that it is going to have some trouble here and there, but we could definitely have some changes. I believe that we are going to have some issues on the long run, and for that we need to figure out a way other than "if you buy bitcoin, it will go up in the future" type of convincing, we need something bigger than that to grow.
The only thing other than the growing price of Bitcoin is the use cases it provides to its users that can be used to convince people but that is not going to be as effective as the price because most people are adopting Bitcoin not for its use cases but because they see it going up and they believe they will get good returns if they buy Bitcoin right now. If they see that there is absolutely no growth, or even if there is, it isn't significant enough to provide them any profit, they will barely be interested.
So, if there is no growth and no bull run for 10 years, the pace at which the adoption is going right now will decrease greatly, and we can barely have any way to convince people to still buy Bitcoin if they don't see any incentive connected to it and that will surely affect the adoption rate that we have.
