Even today, a Yoda X coin was listed to the 50x exchange, but only in IEO mode at the request of the creators of this coin, this means that only the project team carries out the initial sale on the 50x exchange. All participants in this project have the opportunity to register on the 50x exchange with promo code 32643 and get 350 A2A coins, which will definitely be enough to pay commission fees when buying a coin!
Sorry, which exchanges did they list? I did a search but I still couldn't find the information you saw, please share so I could see it.
Name of the exchange is 50x, look at the link to the exchange in my signature ore in this thread:
