While holding your cryptocurrency on an exchange does carry certain risks, I feel that it is one of the better options for those who are less technically adept. For crypto to go mainstream, we need to have robust and user friendly trusted third parties like exchanges that can take care of these things for the average user. Bitfinex is another exchange that has committed to providing EOS token swap support. In fact, these guys are really into EOS and have invested in a few projects related to it including a decentralized exchange built on EOS and seeking to become an official EOS block producer and more. Here's the relevant announcement for the token swap: http://blog.bitfinex.com/announcements/eos-mainnet-token-swap/
