I bet there are some millionaires in mom's basement, teens who have BTC but don't know what to do with it. Think about when you were younger, it would be hard to figur eout how to sell it, and do things like taxes, and your parents would be all over your case to figure out what BTC even is...
It would be a very disciplined teen to have held on since the early days. I'll bet an awful lot of coins were squandered or lost long before we reached today's price levels. It must be a sweet feeling if they did sit tight.
I started hoarding silver coins when I was seven. My grandpa taught me collect them from change. I didn't understand about inflation though till I was about 10 and didn't understand the why of inflation till I was about 12.
Another relative told me to save money in a bank earning about 3% interest. He put $5 in it for me. In about 5 years, it was only about $5.79. I noticed that the price of a candy bar had gone from 5 pennies to 25 pennies. It was then that I realized that saving money in the bank was a really bad idea. Only saved silver after that. I had over $300 in silver coins by the time I was 18. Sold most of them around $40 an ounce around 1979 just before the Hunt Brother fiasco. My parents needed the money to save their home.
I was upset that they never paid me back, but just let it go. Over 30 years later though, they gave me a piece of property in Hawaii with a cabin on it. So I guess saving that silver paid off in the long run after all.
