I just tried to make a bull post about Pokémon and the broader TCG market, but I simply wasn't able to.

Not because the market isn't exciting, it is. Probably one of the most exciting asset classes out there right now.
But because I literally spent hours trying to find basic market data and couldn't:
How big is the market?
Depends which research firm you ask, estimates range from $8B to $50B. Nobody actually knows.
Daily volume?
Doesn't even exist as a metric.
Price of a specific card right now?
Check eBay, TCGplayer, Cardmarket, three Japanese platforms plus a Discord group and you'll get six different answers.
This is a market where authentication means mailing your card in an envelope and waiting 3 months. Where a $20,000 transaction settles through PayPal and a handshake. Where counterfeits make up an estimated 15-20% of online sales and there's no reliable way to verify what you're buying.
Tens of billions of dollars flowing through infrastructure like the internet was invented about 2 weeks ago - in a market growing double digits % YoY.
If that doesn't scream opportunity, I don't know what does.
