Ccbtc exchange is a world known trading medium that allows for trading of fiat crypto and also crypto to crypto trading format. Since the exchange went off, no news have been received from any officials about the reopening of suspended trading activities. But I am so shocked, it seems the exchange is back active, because the previous trade it finished was shown in the website. But I think this act was not real because announcement should have been made if truly the exchange was back online. This exchange is considered as a dead exchange because it suspended it activities since 2019, this signifies the the exchange won't come back again. I advice traders to prevent trading in such exchange.
