After 9 years in the game, CoinEx is shutting down for good — new sign-ups stopped Tuesday, full closure by December 22. The Hong Kong-based exchange points to a brutal extended downturn, thinning volumes and liquidity, plus compliance costs it says got out of hand. If withdrawals aren't already sorted for CoinEx users, now's the time to move. Not the first exchange to fold under this pressure, won't be the last.
