Short answer
No. A copied trade pays the same fee as a trade you place yourself, from 0.45%. There's no copy markup, subscription or profit share.
Fees do add up with activity, though. Copying a trader who trades dozens of times a day means dozens of fees a day. Check how often someone trades before you copy them, and pick an amount per trade where the fee still makes sense.
When you're copied, 10% of the fees your copiers pay goes to the trader they copied, out of our share. It doesn't cost copiers anything extra.
