Scammers are the major problem of todays crypto. In my opinion, if there would be less scam projects in the industry, we would definitely reach the mass adoption much faster. People are afraid to put their money into crypto, because of its bad image.
People are still afraid to invest but things have change since IEO took over fundraising since the beginning of 2019, people have become less scared of crypto investment since then, thats why we see IEO projects selling out in seconds to minutes on big exchanges
