As a developer I don't trust the team, it's clear there are problems and the situation it's pretty scary, they postponed the Zerocoin implementation from february to april but devs are not working, check yourself guys, in GitHub repository (
https://github.com/Solaris-Project/Solaris/) the latest commit was ONE MONTH AGO (Latest commit 5294ddf on 28 Jan), too much in this field, expecially if you have to respect a promise......
I also don't trush that developer KEESDEWIT, he can't make working stable his first coin AMS (Amsterdam Coin) its wallet crashes all the time after switch to PoS and I suppose XLR possible will have same problem since PIVX codebase is not tested enough and need an experienced dev with free time to support it and fix at time, that KEESDEWIT is not such dev obviously.
Also how I already said many times - after restart the wallet (AMS, XLR, any coin on PIVX codebase) it needs to reindex all blocks. Well for now it takes ~10 minutes, but in the future (with more blocks) it will take more and more time! It needs to be fixed, so PIVX codebase should be fixed before use on serious projects.
