There comes a time in the life of every exchange platform to be tested out for it's resilience and strength in the face of adversaries. The CPU Finex was one who couldn't come out of the box of problems a new exchange platform faces. Currently, CPU Finex cannot be used as it's website is not able to be accessed as the website has been closed out of access to the people. The death of the exchange culminated into the lack of utility for it's CPU token. The token on the other hand still trades on a number of exchange which tells me that they had a good backings of the users who used it's platform beforehand. If you had intentions of using this exchange, then you will have to look for other options as the unavailability of this exchange could breed scams which one could fall victim too.
