Answer: Yes, the same assumption can be made for tzBTC, uBTC, and ctez. These are all forms of Bitcoin (BTC) that are denominated in different units. For example, tzBTC is a unit of Bitcoin that is denominated in Tez, uBTC is a unit of Bitcoin that is denominated in microBitcoin, and ctez is a unit of Bitcoin that is denominated in ctez. All of these units are interchangeable and can be used to purchase goods and services, as well as to trade on various exchanges. Ultimately, the value of each unit is determined by the market, so the same assumption can be made for all of them.
