I sent 2.10679394 BTC from GDAX to my KuCoin wallet (18PsEQm6HWNKX16n7HRoKme6MpuLoz6CPJ). I received only 2.02931784 BTC on 2018-03-30. Receiving amount is incorrect. So, I looked up the transaction on Block Cypher: https://live.blockcypher.com/btc/tx/d70dbd30cd20a92426d603066aa13ccb50517488d4e71c8ad68108ba86d60200/ and see that my 2.10680943 BTC was spit into two outputs: 2.02931784 BTC and 0.0774761 BTC.

Do you know why I lost 0.0774761 BTC (bc1qkg7kd8nxdu6lvhd9amj8kgpd5juxq3c436hrl3)? Other BTC address explorer: https://blockchain.info/address/3LoYZM66bREsdgTB1MCuBTFNbCBbpvPAww

On Block Cypher, it says:- Fees: 0.00001549 BTC

Newbie here; still learning.

Thanks.

I'd suggest you contact their support with this information to see what they say.

It looks like the extra funds have gone to them as change or have been sent elsewhere (by them) either way, this is their issue and they should fix it.

Thanks. Yes, I opened a ticket with Coinbase as soon as I noticed this. Your reply will be helpful in communicating with Coinbase now.
