I strongly recommend reading for you instead of posting here. 

The concerns I kisted in my post are not personal, they are common concerns among cryptographers including bitcoiners, Check this one for instance https://git.libssh.org/projects/libssh.git/tree/doc/curve25519-sha256@libssh.org.txt#n4

It is very bad attitude to talk about subjects that one has no background about. In the context of this topic, disclosing public keys is not recommended by prominent bitcoiners exactly because of the security concerns I've mentioned above and your comment is not only worthless but also misleading and causes confusion. Drive safe.
