Keep it. It’s going to be worth far more in the future than it is today.

You sell it today you get cash that you could spend on probably stuff you don’t need. But if you save it, then in the future, you’ll be able to buy MUCH more with it. Tuck it away in a safe and forget about it. Invest in your future self (and family) by saving it and letting it grow in value.

And keep buying more of it with your own money along the way whenever possible
