I'm ready to create BitIRR and pay 200k BTs for it.
1- How many BitIRR will be created? Do I should decide for that?
2- Do I should create it through CLI?
3- Is that all of this Asset at the beginning belong to account created it?
4- How can I or any other Iranian entity can be a gateway for this asset?
5- How many witnesses should convince to publish prices? 51?
1) None will be created! Please read the whitepaper at docs.bitshares.eu/
2) bitassets can currently only be created through CLI wallet
3) BITassets belong to the network .. only "privatized" bitassets belong to
someone else
4) That's mostly a legal and liquidity issue. You should definitely have some
technician that has alot of knowledge about the bts blockchain.
5) Not, sure .. but I think you need at least 51%(!) .. so just a few.
6. Is it required for BitIRR to have price updates only in BTS?
7. Is it possible to have it in BTC or USD or something else?
8. Or is it possible that we have absolutely no price updates? Only gateways act and deposit and withdraw IRR in 1:1 basis
9. How is the bitIRR asset created
10. how is it support by comunity
11. how is it deposit and withdraw by gateways.
6) Yes. Required!
7) you can trade it against USD or BTC .. your choice, but you need to borrow it
from the network using BTS! (* this is only true for MPA, not for privatized
bitassets)

Not possible. You are asking for an "I owe you" (IOU)
9) It's a special command and no actual documentation is really available
besides the code comments.
10) bitUSD is well supported .. what do you mean?
11) Via BitShares account
