Does it still need to short dealing with only cryptocurrency ?
I don't think I understand the question. Can you elaborate?
Time for transfert a far lower between market when dealing with cryptocurrency only but still need one or more hours to confirm transaction.
But i understand it's totally out of bot's strategy to perform any transfer between markets.
Yes that's correct. Since we want to be hedged against the market, the two orders (long and short) need to be executed as fast as possible. If we need a USD/CNY conversion before it will also have to be exectued as fast as possible. As you mentioned there is no money or bitcoin transfer in this project so the hours needed to confirm a transaction don't apply here.
