It will be interesting to learn more about how the CRA deals with this hooey. If he was "gifted" $1.3M, that would be taxable income and he would have to give the government about half. Is an NFT an investment that you can declare a loss on? If not, he would have (should have) paid ~$650K in tax to own an item that is worth a tenth of that now. If he can declare the investment loss of 1.2M, that unwinds much of the tax (still not all though as he is getting capital gains credits and paid income tax).
He has multiple corps, LLCs, holdings, etc.. and a bunch of other avenues that most have never heard of... in multiple countries. The transactions may not even involve the cra.
1.3m nor the taxes he may, or may not, owe on it.. are worth a second thought to him... if he even knows about it.
