Don't worry, prices will keep rising but it's an interesting story, I myself should have held when I had the chance but we have to learn somehow! It's taught me to be more informed and keep learning more about the blockchain. And steemit is a beautiful platform for keeping up to date and learning new things.
I also have a depressing story about the time I got a load of ETH in the presale and sold when it shot up to $30, but Ill save that for another day!! I agree about staying informed but for me its always been a hobby and interest thing, its just that my hobby is now worth more than my savings!!
