There many exchanges where CLAM wallets not works for long time (few weeks)! It is Polonex, Cryptopia, YoBit.
As well, CLAM delisted from integrated in coinomi exchange and You Can't exchange on ShapeShift CLAM anymore! No any comments from support.
Not any explanation I can found anywhere!
All of this is really scary signs!!
I am Experienced crypto investor and trader and can tell you
You know that Shapeshift plugs into Poloniex and Poloniex fucking sucks.
Not sure what the deal is with the Coinomi shit... I've not followed their stuff at all even though they get a fair bit of CLAM traffic from FreeBitcoins.com
YoBit is scammers.
Not sure about Cryptopia either... only found them not long ago.
