What are some potential obstacles in mainstream adoption of Monero?
I wanted to learn about what potential obstacles would Monero community face if (hopefully *when*) Monero sees mainstream adoption? And what are the potential/proposed solutions to them?
For example, how would Monero blockchain scale? If vasts numbers of people were to use Monero, the blockchain size would increase so much, that the group of entities running public nodes would become rather exclusive, no? Are there any proposed solutions to that at the moment?
