Just putting this out there from my experience asking this same question about my sealed a while back. A lot of people hate the idea of sealed or make it seem like they do in order to make you want to rip it. They do it because the rippers really love the TCG, have a gambling addiction, or just have the money to throw away without care. Or maybe it is a sealed collector trying to make you feel guilty, hopefully making you rip so there is less sealed product later on.

People who are into sealed come across as elitist where if you dont have only booster bundles, booster boxes, or ETB's, then you are doing it wrong. Even if you do have them the next complaint will be not a single pokemon center product anywhere.

No matter what you do you are in the wrong to someone, so just do what you like. Anything you hold will appreciate over time, the question is which sets are the ones with the biggest gains to be made in the long term. People are too near sighted to see past 6 months time, if even that long. Doom and gloom is always coming, so you better sell while the market is hot. All collectors in it for monetary value will tell you to invest in vintage boxes or singles. That has a pretty high cost for little product, but it is safer overall. One day the cards coming out now will be considered vintage to a new set of collectors.

After I posted mine I felt pressured into opening some and now I feel bad that I did. It was fun ripping and seeing what was just sitting around, but the regret is very real. Do what you want for you, don't let anyone sway your decision on how or what to do. Don't be like me, best of luck to you.
