Don't hold your breath, it's Turkey and Erdogan we talk about:
Turkey’s President Recep Tayyip Erdoğan has stated that Turkey’s cryptocurrency law “is ready” and will be submitted to parliament “without delay.” Turkish President Recep Tayyip Erdoğan said at a meeting with journalists “The law is ready, we will send it to the parliament soon without delay.”

Turned out to be a nothingburger one and a half year later, this will be at most slightly different.
In my opinion, crypto taxation would be a great challenge for the government in tracking our transactions especially when it involves the cryptocurrencies that we have in our non-custodial wallets. Usually capital gains and/or realized income would be the main basis of computing our taxes when converting cryptocurrencies to fiat money.
That's what they are aiming also, they don't give a damn on the coins you hold in your wallet they are targeting specifically exchanges and capital gains, and for a trader you simply have no way out of this, let's not even mention DEX, it's not there were the real money is made, it's all in CEX and they know they can grab that data with a single click.
Turkey is going in the wrong direction. With one of the highest inflation rates in the world, they first banned payments with cryptocurrencies, and, as it usually happens, as people skipped the ban they have realized that it is better to regulate them and try to tax them. The problem is that if you put high taxes you incentivize people not to declare. If instead of 30% they put a 5% tax almost everyone would declare because for how cheap it is it is not worth getting into a potential problem with the tax authorities, but with how disastrous Turkey's monetary policy is going I am not surprised.
There is only one flaw in your reasoning, you assume that if you tax something by just 5% you will have a flow of grateful citizens who will be on January 1st on the stairs of the IRS to pay up. I don't think there is another region in the world that with the same income and education has the same hate for paying tax and the same affinity for tax evasion as southern Europe and that part of the middle east, if it's one thing Greece and Turkey have in commons is their hate for paying a single dime in tax, and you can see what that has lead to in both cases.
