Taxes can be complicated, and especially so when it comes to tracking gains and losses. If you stick to centralized exchanges it can be easier, but to get better yields you will have to venture into the world of DefI and things quickly can get out of hand. With blockchains being a perfect ledger, once the tax authorities link you to an account they can quickly track things back and will know your full history and can then see if you did your taxes right.
