There are really difficulties in using bitcoin and this is why it could have difficulties in being adapted. Aside from the scammers that are technically good in making fake sites or phishing sites, doing fraud and etc. might be difficult for bitcoin to be adapted by the community. However, in every problem that needs to be addressed and if there is a willingness for a change it could happen. I think there will come a time that bitcoin dev can get the idea on how to minimize, eradicate and keep bitcoin funds safely without being compromised by technical issues and bad elements.
