If I buy crypto noncustodial, I have to pay >50 % tax on gains, when i off-ramp/change wallet/swap/buy anything with these cryptos if they've appreciated in value since I bought them. If I have another wallet, where the coin has depreciated I can not deduct the loss from my above gain.

So, where I live multiple people have been bankrupted by buying and selling crypto, unaware of the tax laws in their country.

If I bought an crypto ETF I would only pay ≈ 25% and my loss would be deductible.

Just consider that sentiment structure for brief moment...
