I have some FCN and other cryptocurrency in this wallet all offered be freewallet.org and I know Feewallet.org offer wallets for absolutely all coins. But the risk is very high as you have no control over the keys. And their wallets are constantly down most of the time.
I’m still testing their services and will provide a full update soon. But at this stage if your unable to find the right wallet for that cryptocurrency carry on using freewallet.org with caution otherwise leave in the exchanges till a safe option is available.
