I do not have link of this information, I see right here in the btctalk forum, so because ESPERS is a currency that has been enduring for a long period of life I believe in it, let's see that we have few exchange listings, I imagine that getting at least 5 exchange we would have a large volume and a diversification of users worldwide, mainly Chinese, American and European exchange, I have been following this project for years, and still bet on it, in this period there have been many scammers, and ESPERS is still alive and walking , soon with the growth of new exchanges and the knowledge and credibility of bitcoin and blockchain espers will have its space, this is a matter of time, only thing I ask the ESPERS community and patience and the Developers to continue and update and invest in this project.
