Gosh. Is this one of those tiktok quizzes? At start you had 10 bucks and he had 10 bucks worth of crypto for total assets of 20 Now you have crypto with value of 0 and he has 10 bucks for total assets of 10 Overall 10 bucks is gone and yes there are winners and losers Edit: TikTok quiz abbreviated: you buy for 50, sell for 60, buy again for 80, sell for 90.
