Hello,
I think this might be of interest for you:
Yesterday afternoon (CET) we have made a test transfer of 0.1 BTC via BlockTrades*) for exchange in BTS and to credit our account "armin39" at BitShares. It took over 20 hours until that amount was credited to the account.
A similar test transfer via Metaexchange was done in less than half an hour.
*) The email address 'support@blocktrades.us' shown on the BlockTrades website does not work!
Best regards,
armilo
