Once the pre-sale is over, your purchased CRSALE tokens will be converted to Crypti, based on the amount of CRSALE you hold, and the total funds raised on the pre-sale. You could then withdraw them to you Crypti wallet.

We have worked out a solution with Bter to support this (using buying dates and times).
