You are young but you are so smart at age of 13 you buy bitcoin and you want it to hold. Good for you my dear. Hold your bitcoin and you will wait at the right time to sell it. I know you have a big faith on bitcoin thats why you invest in bitcoin.
I wish I was that smart when I was 13, if this young person really decides to invest in bitcoin and it is capable of holding his coins then he will surely become a success story in the forum, however as we know it is not easy at all to hold our coins especially when the price crashes like what we saw some years ago, so as long as he also believes in the technology and it is not here just for the money he will do fine but if he only cares about the money there is a chance he will lose it if the price crashes.
