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?
I personally do not like regulations and I don't think it can in any way help in the mass adoption of Bitcoin if that's the coin in question, regulations are even inimical to the growth of the network, these regulations are imposed by the government and it's basically obvious that most of this governments do not want the Bitcoin network to attain mass adoption, just because they can't control it and cause it puts control in the hands of its users, I don't think there's any of such government sanctions that is channeled at making the network better, it's all in a bid to quell its development, make it difficult for people to use it and in that way make popular their central bank digital currencies.
Bitcoin does not really have to be stable to get to mass adoption, volatility is even an aspect of the network that most of its investors like, and it can be a reason why more people get allured to the network, I believe the best thing for mass adoption of Bitcoin is when people understand the importance and benefits of being their own bank, that way more people will appreciate the relevance of the network and would want to use it, so as to control their finances and take it a bit away from the hands of the government.
