People who fall the scam patterns you mention into are certainly aware of the value of BTC (probably ATH value) but the actual value of blockchain it is operating on. Greed is the factor of attracting people towards any kind of scam which is essentially true here as well. In order to protect crypto ecosystem, people need to be educated with actual use cases of blockchain and various apps utilizing this technology. It is not easy to explain such stuff as compared to Banking.
As frontliners, local exchanges can play a vital role educating people about cryptocurrencies and protect entire ecosystem. The trust is another thing people are not believing in cryptocurrencies held by exchanges. Asset insurance and nominee introduction can become the next major beneficial factor for mass adoption.
