This is very helpful thank you.
My bitcoin is being stored in an exodus wallet and I can't remember how I bought it.
I will have a look at binance.
The best chance for you to buy BTC due to the possible age restriction is using a P2P exchange but I'm surprised how a teen who is yet to have parental responsibility will forget how he/she bought BTC days ago. The only way this is possible is either there is something you're not telling us or you're not ready to get involved in Bitcoin
