The prices are listed as ETH only.  Just as it has gotten more expensive, it can also become cheaper.  We are firm believers in the space and operate in crypto as much as we can. 

Also, tokensale ends on December 1st at 10PM KST!  You can see the current status on https://www.proofsuite.com/token.  It will also become tradable at this time and there is a listing on Etherdelta although we recommend holding on to it at least until the AMP releases as the token gives Eth rewards.
