* FIXME
*
* This is not working and cannot work simply because this "NONE" type doesn't exist during a sync,
* as well as subOperations which are never created either.
*
* And even after fixing this, we're getting wrong fee estimation for TRC20 transactions
* which are considered as 0 all the time, while it always being between 1 and 10 TRX.
