Ask HN: How to Proceed Negotiation?

I am currently being offered 65k TC for a mid sized VC funded company in Europe. I am already earning 74k at my current job and I was really expecting them to make me a higher offers because I told them upfront. I reminded them of my current salary and said, that I can't even consider taking their current offer. They went back to do internal discussion. I fear, that they will come up with a new offer matching my current TC. However I would only consider switching, when there is an actual premium in comparison to current TC (let's say 80k and I am in). Do you have tips how to react? For context: I am also in the interview process with two other companies, which seems to offer the salary I am aiming for. However I have not yet arrived at this stage.
