I have a same problem. I sent 11,912 XRP on 12/23/2017 from Kraken to Bithumb. As of today, 1/22/2018 I still did not get XRP into my Bithumb account. However, the transaction and tags were entered correctly and processed. For some reason, Bithumb is not able to deposit into my account. Meanwhile it went up close to $4 and missed the selling point. I called, wrote numerous times to Bithumb, but all I get a boiler reply.....
I did send XRP from Bithumb to Kraken without any problem before I sent it back to Bithumb with all XRP amount
