I love Waves and what they do, but this notice regarding Waves on Cryptopia makes me a bit sad:
WAVES / BTC market is closing
WAVES team failed to notify us of two recent WAVES updates (0.7.6 and 0.7.7). Both interact badly with our wallets environment and the lack of communication regarding updates is a cause of concern. We are currently discussing the best option moving forward with Waves and will update our users asap.
