It is not possible to hide your steemit wallet from the public,yeah the public can see your steemit
wallet but they cannot have access to do
transactions on it if they do not have your
password,so that is why it is very good to keep
your password safe because if anyone have your password then they can easily access your
steemit account wallet and steal your money...you
cannot hide your steemit wallet,the way the steem blockchain is is that every activities you do
on an account can be easily seen by absolutely anyone so there is nothing to hide about your
steemit account and i think no one should be
bothered about as long as you are not doing any criminal activities on steemit
