Just did a test transfer of 10 DERO to stocks.exchange with "normal" priority and a ring size of 5; let's see how long it takes to show up there.
EDIT - I also transferred some TZC at around the same time and it showed up about 15 minutes later; nothing but crickets with the DERO deposit so far.
Maby the exchange daemon is stucked at block 17022? Dev?
