Privacy and security is still not at good structure, it should be defined protectively without affecting the end users meanwhile cheating should be avoided in the name of same privacy and security measures.
Privacy and security is good, crypto is a decentralized system, so you can be private and as far as security, if you know and educate yourself then you should be good. However, if you used centralized exchanges like Coinbase, then your privacy has been compromised already since there is a mandatory KYC and chances are, they are going to cooperate with the government, exposing your identity.
