I contacted Paul Lerner who is one of the escrows. He and his lawyers are willing to help us to get our investment back. They need information and evidence from more investors in the ICO.

Please send messages to him through facebook at

and you can join the telegram group below for discussion about refund

Do you mean he locks up our fund to make profit for himself?

I sent several emails and contacted A2B direct on facebook, but no response at all
I also messaged Dmitriy Kryshtal on facebook directly on 21 Oct. He said he would handle it.
However, I still have not received refund until now and he does not reply to my messages.

Hi A2B Team,

I haven't received my refund yet. Is the refund process still ongoing?

I have already contacted you through email and facebook, but no response yet.

Great project. I have participated in the crowdsale and hope you will gain more attention soon.

As I know the contribution is measured in BTC, BTC's forking on August will result in BTC and BCC (bitcoin cash) and their values are split.
In case, the project is not able to reach the minimum target/soft cap (Of course, I don't want to see it happen).
How would you handle the refund? Would you refund both coins?
