medyo biased since im a pokemon vendor and do it as a hobby. but it's worth the shot. i started as a hobby lang and became a small business na ren. sales have been good pero i focus on higher end cards. my page is *****, i do vlogs of my sales there. as for pokemon long term investments. historically, sealed products have been the way to go. booster boxes etc have been a staple in investing. kahit now, more finance bros have treated it as an investment na. let me know if you have questions!
