The major exchanges being closed was also the topic of one of my recent Steemit blog posts. Please check it up: https://steemit.com/cryptocurrency/@smallstepschange/cryptocurrency-major-crypto-exchanges-offline-or-halting-new-user-registration

I don't know what to think about Etherdelta. I heard that it is quite complicated. And that prices are higher than on the other exchanges.

Maybe it is a good idea to quickly register accounts on all the major exchanges - just as a precaution. This way, it cannot happen that you cannot register when you want to: https://steemit.com/cryptocurrency/@smallstepschange/cryptocurrency-be-quick-register-your-account-on-the-major-crypto-exchanges-as-long-as-you-can
