From the GRX Telegram Official:
Listing of GRX Token and wallet integration in progress on Livecoin exchange -
https://www.livecoin.net. Please wait for confirmation before making Transfers. Thank you
I would say hold off on any external exchanges until there is a product first. (Too late, I know)
After you have a product (lending) each new exchange listing would generate a bump in price as the doors are opened to new investors.
Without the product first, the opposite happens as seen with current price.
Hoping for the best though!
