I just saw this topic "What problems in Bitcoin's infrastructure prevent it from being adopted more easily?". All the answers were really interesting, mentioning the lack of regulation, volatility, ignorance, etc.

My question is: How can these problems be solved? And is it ever possible, what do you think?

In my opinion, regulation, practicality, and stability are definitely required for the mass adoption of crypto as a payment method/currency.
What are your opinions on this?
