Short answer: Travel — football streaming is increasingly paywalled. $10 buys 1 day in 100+ cities. Football match tickets average $30-300.
Mathematical answer: $10 buys you 1 full day in dozens of cities globally (street food, hostel, transit included). $10 in football: maybe 1 month of one streaming service. A live match ticket: average $30-300+. On pure value-per-experience, travel wins. But for football fans, TenDollarPick lets you do both: build a $10 squad AND plan a $10 trip.
