I tried to convert BTC from Coinbase account to BCC (Bitcoin Cash) in my Freewallet BCC wallet using Changelly. Instead of sending to Changelly address, I mistakenly sent directly to my Freewallet address which did not receive them.
Are the coins lost or is there a way to get them back?
You sent bitcoin to a bitcoin cash adress on your freewallet? Do you own the private keys for the adress you send them to?
If so, simply import the private key in electrum if the above is the case, or import it in electroncash if it's vice versa.
If you do not own the private keys that are associated with the adress, but rather the owner of the wallet (( Freewallet??) never heard of them by the way)....
you will need to contact their support and ask if they can do anything. Which they probably can, but i doubt if they're willing to put the effort in it.
