What happened to Ember? Why Cryptopia closed the BTC/EMB market?
"Due to the inability to maintain a price higher than the market 1 St Emb/BTC is closed. Please use the market emb/LTC instead."
Ah, basically that market was dead, so they had to close it down for the LTC market instead. The lowest EMB/BTC could go was 1 satoshi, but the real price was like a quarter or a tenth of a satoshi. So nobody was using the BTC market, or if they were they were overpaying by 400%, so Cryptopia shut it down in favor of the EMB/LTC, EMB/DOGE market instead.
