It's not tax evasion to pay with a payment method that doesn't have taxes applied to it.
There are situations where certain taxations do not apply, but simply paying with crytpo currency does not change a transaction from taxable to be tax free.
By the way, what's your problem with Bitcoin?
https://www.statista.com/statistics/881541/bitcoin-energy-consumption-transactio...
1 bitcoin transaction is roughly 1000000 visa transactions in electricity.
Paying with bitcoin on the chain produces costs equvalent to running an electrical heater for 500 hours. Even if you produce the electricity somewhere, where it is currently "cheap", that is still a huge waste of energy. Huge is too small a word for the comparison. If you compare things that should do the same, there should be percentages, like oh, credit card uses x amount, paypal uses 100% more, so it is environmentally friendlier to not use paypal, but credit card instead. That's a factor of 2. The factor when comparing to bitcoin is 1000000.
That insane imbalance does not even change, if you cut off a zero or two by using more efficient methods.
The costs are hidden away in the stock market price of bitcoin and in the financial losses of people trading bitcoin and losing money. They are also hidden in the cost of "mining" the coins. That's even more electricity waste.
It is not sustainable to hide away the costs (Not sustainable means, that it will crash someday). Someone has to pay for it. And it will be the people that have bitcoins as an investment, when bitcoin falls under the price they paid for it and they suddenly need real money. Oh, and it is the planet, because of all the energy and rescource waste.
So yeah, I kinda have a problem with bitcoin and crypto in general. It is wasteful in an insane way.
The irony is, even if you could overcome the costs somehow (you can't, it's crypto, it needs to be computational hard, else it is not crypto), the currency is not fit to be a currency. Too volatile. So the topic here makes sense, asking for "stable" coins.
But "stable" coins are an illusion. At best it is an escrow with extra steps. You buy "points" with money from an entity and that entity will let you spend those points at a seller's account. And that seller can exchange those points for money again. Obfuscating this with "crypto" is a marketing scam to lure people into believing this is crypto, the crypto they heard in the news about. It's not. You can't mine it - if you could, it is not stable. It is not decentral and independent from companies. So it has even less intrinsic value than crypto. It just has the name coin in it. But in reality it is about the same as if you would load up your paypal account for future payments. So you instead load up your crypto stablecoin wallet.
