rich people and wealthy countries have a lot of advantage in either doing Hodl or doing day trade, imagine that someone rich would take 50 million US dollars and buy bitcoin for the price of $ 10,000 and decide to do hodl for many years, that person will be richer with this big increase that the bitcoin price had... that old phrase: "money calls money" that in my country many people like to talk. when someone doesn't have a lot of money and invests and then bills appear to pay that person will withdraw the investment money to pay bills
a small bankroll Is a headache, the person has to work hard and the profits are few, which makes it very stressful. the same applies to making Hodl, imagine that the person has $50 and decided to buy bitcoin for the price of $54000 to make hodl, if in 2023 the price of bitcoin is $150.000 that person will keep $150, waited more than 1 year to get $150. Is a little demotivating, unless the person invests in some altcoin that generates 10X profit in that case it would be worth just making hodl with small amount of money
