II've gotten to see many exchange platforms that gave numerous excuses to take out some time before coming back, but never came back. I feel their purpose of leaving is not due to poor maintenance or bad leadership but for their selfish desire. This is because most of these exchanges must have gathered enough trust from their traders before taking such silly excuses, thereby giving them access to these traders funds.
One of these exchanges is known as the BCEX Korea. This time around, the excuse they gave was "maintenance." They promised traders that this maintenance would be finished in December 2020 and up until now, we haven't heard anything about the exchange platform as their site isn't working any longer and there no news about them any longer.
