Try and ignore negativity!! Just focus on releasing the wallet asap, even if it has a few bugs, release as beta.
Reality is, many many scams in crypto, so we all have to accept that when things don't go to plan, some people call scam. Just ignore it!! As soon as people see 'evidence' that ReserveShare is real people will get positive again.
Until wallet is released many will still support you based on gut instincts. Once you release the wallet, or even more evidence it exists, majority support you too. If you can't release more evidence that wallet dev is ongoing, ignore all negativity, and spend 100% of your time working towards releasing the wallet.
Engaging trolls will not benefit your project. You can't win doing that, only releasing wallet can do that.
