I've used viabtc which requires only 1 confirmation to start trading BCH. But you'll have to wait for 20 confirmations on your BCH deposit to withdraw (BTC for example).

It finally worked thanks. I have 3 confirmations so far.

For anyone trying to send multisig BCH, I just followed the instructions on this page after installing Ubuntu on an old laptop I had...

browse to this page:
https://github.com/fyookball/electrum

Follow the instructions under Development version:

git clone git://github.com/fyookball/electrum.git
.
.
.

I had to install some dependencies such as pip etc which wasn't installed on my system.

On the same subject, I had bitcoin in a multisig (2 of 2) wallet using electrum before the August 2 fork. How do I send my BCH? Electron cash does not provide support for multisig I believe.

I have moved bitcoin to new wallet as per the advice provided, but do not know how to proceed from here.

Thanks.
