We can add to more technological developments as a pro to having more awareness of bitcoin. The benefits of blockchain technology will be exploited by more industries, even now some companies are choosing to use this technology to their advantage. Once bitcoin and blockchain technology becomes mainstream, many more other corporations will utilize this to have better operations.
Cons: people trying to make scams, people who are not very aware of how crypto works getting scammed or losing their money by investing at the wrong time or in the wrong thing.
Why would scams increase once there is more awareness? I think the opposite would happen. Once people are more aware of bitcoin, they should know and be able to differentiate what a scam is from the real thing. Also, enforcing bodies like the government and police can take action towards scammers if there is an increase of awareness and use of bitcoin.
