Please explain what will happen in this situation.
1) I send 2.049 BTC to ChipMixer and choose to get a a voucher.
What kind of voucher(s) I get? Is it one for 2.049 BTC or two for 2.048 BTC + 0.001 BTC?
2) Another mix, I send 2.048 BTC, also choose to get a voucher.
What kind of voucher(s) I get?
3) I want to sweep my vouchers. So I submit all of them from steps 1&2, what are my options now?
Can I specify what kind of chips I want to get? Can I choose 4.096 BTC chip now? Do I have to completely spend the whole value I have in vouchers right now (can I keep 0.001 BTC for the future mix in voucher form)?
Can I choose to make ChipMixer send me the whole 4.097 BTC to my single address in 1 tx (note, it's not a size of a chip)?
Can I choose ChipMixer to give me 1.024 BTC chip privkey? What will happen to the remainder value (3.073) in vouchers? Will I get new vouchers?
4) If I choose to make ChipMixer send me the value I want, what fee do they use?
PS How big is ChipMixer's pool? If I want to mix 100 BTCs in a month will I start getting my own BTC in a week or will they all be not the ones I deposited?
1) You probably get one of 2.048, and one of 0.001, yes.
However you can always split them down. So 2.048 can become 1.024 etc.
2) Correct me if i'm wrong, but that will also result in a chip of 2.048? -Except if they don't have those available, you will get a chip of 1.024 + smaller onces totalling to 2.048
3) You import the privkeys of them into a wallet such as Electrum, then send all of them to another adress you own?
Afaik, you can split down chips, although i'm not entirely sure if you can also *always* group/merge them together to get a higher one (I think i was unable to do so a couple times..?).
Can I choose ChipMixer to give me 1.024 BTC chip privkey? What will happen to the remainder value (3.073) in vouchers? Will I get new vouchers?
You'll probably end up with two of 1.024 BTC chips, and one 2.048 chip that you can withdraw.
4) You decide. they simply provide a private key with the balance. You're free to spend them with whatever fee you'd like.

No one knows, except for Chipmixer themselves AFAIK.
