Hello, I´m 13 and I´m very interested in Bitcoin, because of this I buy BTC. Actually, I've been studying BTC for over a year to invest. Back to the subject, I buy BTC for 9.200 dollars, and I would like to know if you think it´s a good ideia hold btc until it reaches 20.000. Anyway, for now i´m going to wait btc until it reaches in 20.000 for me to sell. What do you think about my opinion? 
God, I wish I had entered into cryptos in your own age. I assume your parents pay everything for you which means you can take more risks and have more free time than the average joe who has bills to pay.
I'd say to invest some of your pocket money every month into BTC and then try to do as many bounties, faucets etc you can in your spare time to accumulate btc and other alts for free. Little by little they will add up and who knows, maybe by the time you are an adult you will have amassed a small fortune! Don't forget though to diversify. Investing in BTC in your age is cool but make sure to invest in yourself too! Study hard and learn skills that you can use to bring food on the table, regardless of BTC's price
