If you purchased your EOS tokens on an exchange and store them in your ethereum address, you must register them by June 1st because EOS tokens will become frozen on the Ethereum blockchain on 02-01-2018 by 22:59:59 UTC. The mainnet launch of EOS system will occur shortly thereafter. Here a simple guide how to register them:

Registered, strapped in, and ready for the moonshot!
Hope that no one loose his token after 1st June or hope many looses their coins so the EOS price pump?
Hopefully, many exchanges will support the swap.
