You draw an alarmist situation, which is not the case when you follow the coin since day one.
There are issue, this is what to expect for early adopters and new protocol like mimblewimble, but this is not that dramatic as you explained.
I understand your frustration papa, lost coins, wallet that don't work well on MAC...
First Bitmesh is delisting, yes, but not only XBG, they are delisting many coins, almost all altcoin in fact
Dear Users,
After review, BitMesh decided to delist the following coins at 2019-6-18 12:00(UTC+8):
XRP, VBK, XBG, TERA, CHI, PATH Bitmesh is changing their business model, we can't blame them for that, there is an other exchange
https://vinex.network/market/BTC_XBGMore will come later, what I mean without bitmesh the coin will survive, this is not a big deal at all.
Communication is getting better, now someone that is not a dev will handle the communication part. Today is a great day to mine XBG
XBG the only MW coin with sound economics.
