Almost all exchange are currently experiencing problems mostly due to high traffic and bity seems to be not an exception to that. Anyways, this is not the first time they disabled trading so I'm sure it'll be back like always.
As for eth, Seems like it will take some time hmmm...
yes it does. ongoing SWAP are delayed. but will arrive as soon as issue is fixed. no estimation of time for now
