I tried both my and my brother's account and It resulted in the same thing, no option to deposit using bitcoin.
I've searched and I couldn't find any articles where Skrill announced that they would delete the option to deposit using Bitcoin. Does anyone have an idea?
Use Neteller instead.
If I remember well there is something with Neteller. Something like you can deposit bitcoins but can't spend it via the card or bank transfer.
Making the feature a simple wallet to store/spend your bitcoins which I doubt the OP is looking for. Maybe the thing changed since, in this case, I would be happy to see someone confirming it
