What does 'do not convert' option mean?
If you have selected 'do not convert' feature, we will NOT convert incoming coins. If your customer pays in Litecoin, we will deposit Litecoins to your dashboard and you will be able to withdraw that particular payment as Litecoin only.
At the moment, only Bitcoin and Litecoin are not converted, all other altcoins will be converted to Bitcoin instead.
By enabling this feature, you will be able to extend your invoice lifetime up to 24 hours.
