No, don't think so. When the wallet will be released in June just a few CHI will get sent to the presale participants only, which can be used to reserve your names/usernames/accounts in the Chimaera blockchain and allow you to test or play Treat Fighter, amongst other things. All other CHI will only be distributed after the main sale, so an exchange listing makes no sense, since nobody has any reasonable amount of CHI anyway.

There was some private presale reopened. Not sure, if US citizens are allowed here, but min purchase is 15k Euro. You maybe want to ask in telegram about it.
