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? 
You're one lucky 13 years old imagine you have that amount at that age and you have that thinking at a very young age, when every boy at your age are all playing mobile legend and doing other stuff online, while you are planning to buy and HODL Bitcoin, if you are comfortable at your investment then you can proceed.
When you reach 18 years old and you're still holding that Bitcoin I'm pretty sure you will be rich at 18.
