"The wallet id designed to convert 10 percent of your total PivX balance to zPiv. If you do not wish to use zPiv functionality, you can disable it by editing the pivx.conf file and adding enablezeromint=0. Do not do it while the wallet is active and running. Another way to do disable ZPiV is by going to Tools > options > increase preferred automin zPIV Denomination to a very high value like 5000."
