what makes the token registration unsafe? it is done by signing in to your wallet of choice (most likely MEW), and performing the actions there. in order to just send ETH from the wallet, for example, you will have the same amount of vulnerability exposure.
as for the problems with hackers and MEW/MyCrypto, those are hardly EOS-specific.
RE: Everipedia should just wait until EOS goes live, because this may not end well in my opinion?
