Coinbase forced me to hold when I was 16

I bought Bitcoin when I was 16 on Coinbase, and almost immediately after they changed their policy so you had to be 18 to use the exchange. They locked my account, so I was forced to hold. I'm sure they would have let me withdraw my funds if I contacted them but I figured I would just come back when I'm 18. Well I forgot about it until I noticed the bull run in february, I logged on and damn… 1,000 percent gains on my 20 dollars. Best investment of my life. Since then I emailed them, they unlocked my account, and I've been DCAing weekly.
