VST tokens are locked to protect interests of all token holders until we are listed on one of the reputable exchanges with sufficient trading volumes. Being able to trade directly with the decentralize exchanges such as Etherdelta, means tokens will be dumped by early Pre-ICO participants as well as the bounty members. We are already working together with lawyers and the industry experts to get VST tokens listed on proper exchanges (top 10) during 30-60 days after the ICO is finished. However we cannot disclose any details at the moment, due to non disclosure agreements.
