We found that sometimes we get "Transaction is not in blockchain" error when broadcasting PING transactions. If your transaction is stuck and shows in an explorer as empty, drop us a line at admin@cryptoping.tech and we'll rebroadcast your withdrawal.
Thanks, seems like tx got through and I recieved my PING in exchange
btw, I heard from my BTCC contact yesterday that they'll be adding DASH and some other Alts in a few months time.
"Hi Otoh,
I apologize for the late reply. We haven't introduced DASH and the other alts on our exchange, but we're planning to do so over the next months. I'll let you know once we do.
..."
What it would be really nice is for Bitstamp to add DASH!
