How it did after you have received the suggestions? Did you follow the instruction that was given to you by the rain discord developers? As per developers, as said if there's a way to go backdoor with that project, they can easily control and modify things.
Unless, they are open source and things they do whenever they change source codes are on the logs like in github or any place where they show transparency.
I stake about 12 coins (Neblio, Mintcoin, Noblecoin, CompoundCoin, VersionCoin, TruckCoin, HoboNickels, Stronghands, Mintcoin, Elite (was 1337), InflationCoin, Bottlecaps, Stackbit, BitcoinTalkCoin, Stackbit, RAIN, OverpoweredCoin, and Proof of Stake coin), and these kinds of wallet maintenance tasks sometimes have to be put off until I have time, which I haven't had the last few days. I'll post to the thread when I do it. This kind of thing has gone on about 6 times in the last year for this coin.
You have a lot of staked coins you might be earning good with those coins passively.
Keep the thread updated what has happened to you and if you have followed the suggestions that were given to you. I hope that most of those problems will be fixed so you won't have any headache anymore with those investments you took.
