I guess op is using BitPay in his mobile device, but KZC hasn't a wallet for mobiles.

The end of support for FTO and KZC
Due to the uncertainty of networks and the questionable future of the Futurocoin (FTO) and KZCash (KZC) projects, we would like to inform you that on 1st March, 2021 support for these cryptocurrencies will be completely terminated. Be sure to check out the FTO and KZC delisting schedule below.
Schedule:
29 July 2020 - Blocking FTO and KZC deposits.
30 July 2020 - Closing FTO and KZC markets. Canceling posted offers.
30 September 2020 - Blocking the possibility of self-withdrawals. Importantly, after this date:
Withdrawals will be made once a month after prior contact with our support.
Funds in your account in the FTO or KZC currency will be deposited into a negative interest deposit account. The negative interest rate is 20% per month. That means that for each month (from October), the number of FTO and/or KZC will be reduced by 20%. For example, if you will ask for withdrawal in October, you will receive 20% less FTO / KZC. If you decide to withdraw in November - the amount of FTO/ KZC will be reduced by 40%. You can find more details in Cryptocurrency and Token Recover Policy.
1 March 2021 - The end of support for FTO and KZC. Withdrawals are no longer possible.
This was long overdue.
The project has been dead for more than a year, who managed to throw off the coins he did wisely, and who did not have time he will regret it, the virgins of this project had money from him and left.
I think we should expect delisting from the BTC-Alpha exchange in the near future
