> Also, if you made a significant amount of money on any crypto, you probably held it for more then a year at which point to capital gains tax is probably at most only 15% (<$441,000 ordinary income). Ownership of other assets tends to have legal documents of when it was purchased though. How does anyone know how long you've held it? You could prove it if it's been in the same wallet the whole time, with the transaction ID, and proof of ownership of the wallet. But what if you transferred it between wallets, and lost the first?
