Hello,
Is your online Wallet on a Exchange like Bittrex?
I had to follow the transaction history on your “cold” wallet three transactions back to find the origin of both addresses.
It looks like you bought 48950.980488 RDD at Nov 1, 2017 10:52:11 PM and yesterday the exchange plattform was sending your 948 RDD from the same address again.
The address is: RgyjxndVP748UQR6pcpgZtRLfP28jriMS7
I think they will remember that and the next time you buy RDD they are sending the new amount deducting 948 RDD to your “online” wallet.
So if you are buying 1000 RDD you are just getting 52 RDD on Ro5N8g7ToixsAjzbmQGofCX1H7MYa4zSk2 and everything will be fine.
This may be less troublesome for them to handle things like that.
I can’t be perfectly sure about this but for me it looks like thats the case.
