What is the CoinTiger tax?

I'm curious, could you explain what exactly is the CoinTiger tax? Is it a fee charged by the CoinTiger exchange for trading cryptocurrencies? Or is it a tax imposed by the government on transactions made through CoinTiger? Could you clarify the nature of this tax and how it affects users of the platform? Additionally, are there any ways to minimize or avoid this tax, or is it something that traders need to accept as a part of doing business on CoinTiger?
