I thinks scams can really harm bitcoin reputation, there are so many scammers in crypto feild and sometimes they used bitcoin to convince there victim so that they can easily get funds on them. I believe that because of the scams people will be afraid to invest in cypto and the trust of the people will maybe decreases and in the near future cypto will slowly down.
Yes, bitcoin's reputation is so damaging that they don't believe it, especially those who are new and who don't know and understand bitccoin more deeply which makes them hesitant to get involved in it.
Scammers will always be around because bitcoin or other crypto is very profitable for them even if they do it in the wrong and cruel way, what is important is convincing those who are new and well explained to stay and want to get involved with bitcoin or other crypto.
