If someone was smart enough to hold that many BTC then that person could buy more than 5225 iPhone 15 in todays date, but there are only few people who really hold more than that amount in Bitcoin and they aren't interested in Apple devices. iPhone is just an example we can compare that rate to many other things and the answer would be similar because the ones who hold their Bitcoin don't really spend them on things like iPhone or anything else.

Only few people knew that Bitcoin could grow so high in value after a decade and that's why creating threads like this doesn't really make much sense to me. But, if someone really invested in Bitcoin even after 2015's then that person would be a millionaire this day if he/she has hold his/her Bitcoin till this day. I agree with the final part of the thread if someone hasn't invested in Bitcoin till this day then that person should start investing in it with further delay.
