this is not safer;the problem is the transaction out of poloniex... here is where you have to pay attention... it is possible that you get an error message after doing email-confirmation, so your coins will not leave poloniex... problem then is, you will not see them in your account anymore if that happens. problem then is, you will not get support from anybody shortly if this happens... this is experience me and some other users made... some users told that they got coins back after 24 h but there also some which are still waiting since three days now...
