Thanks for helping us answer users’ questions.
You are absolutely right, new coins will only be added after the final release.
We are also planning to launch let's say, a Coin List Vote, so the community can decide which assets should be added next.
I like the idea of a coin list vote and planning this after the release is better it can generate fresh problems if a new list is made now and integrated. Voting will allow the community to participate in making a better future, they will feel more connected to the project and help prioritize the most demanded coins.
Overall, I think you're moving in the right direction and don't need to thanks, team I was contributing and reading some posts and made a reply.
Probably the best solution is to set a minimum fixed fee, for example, 0.000005 BTC per transaction
Yep, this can be the best solution, they can set the minimum fee for BTC deals in BTC not in percentage.
