Everyone has their own opinions but you cannot ignore the fact many people became millionaires because of crypto only . If you play it right with as small investment as 1000 you can become millionaire as well so i wouldn't call it worthless. Crypto's and digital currency are the future that is what i believe and eventually all places such as KFC and McDonald will start accepting them when they stabilize. Check out my other blog here KFC in Canada already started to accept bitcoin as payment.
