#Founder reported to have been arrested.
#Questions put to his profile pg, offers zero response.
#Coinex's main exchange token CET has been removed from all mining features and utilities, making the exchanges coin basically redundant.
I'm an investor in this token, this token is COINEXs main pair token, it was promoted by the company to offer dividends via mining, locking and trading, since all features have been removed, the coin itself is now useless until the company decides to do anything.
At this point in time all profit expectations for this token is zero, or sub par.
Do not recommend using the exchange CET coin till the exchange makes moves to formalize changes and new adoptive utilities to this coin, if.......that ever happens "at all"
Beware everyone! This site has fake volumes, spoofing etc. Also if you deposit ETH it goes missing as they dont use smart contracts, even though that is what ETH is built on. In other words, don't deposit anything to this site. The CET driven mining etc is a scam. They own 80% of CET and just sell it off as every client buys it up. Support takes 1 week to respond and that is only if u jump up and down about your request or it is just ignored. I am waiting 1 month now for a ticket(request) for help about a missing deposit. Kiss that money goodbye.
Don't say you haven't been warned!
During the “Trade-driven mining” period, CoinEx will allocate 80% of our transaction fee revenue as dividends to CET holders. When the mining period ends, all 50% of the total CET supply for free allocation will be distributed and in full circulation. To guarantee the sustainable development of CET and interests of CET holders, we decide to release a long-term dividend allocation plan by which CET holders will continue to receive dividends after “Trade-driven mining” ends. 80% of our total revenue will be allocated to CET holders and the remaining 20% is kept for CoinEx
CoinEx has been on the market for less than a year, but it already made some buzz in the cryptocurrency world because of heavy emphasis on Bitcoin Cash from the beginning.
