Ivan — Predictions & Current Events@IvanCryptoSlav

Humbly disagree. Trading is a single-player sport. Yea, we can hit together and you can give me tips on my forehand. But when it's time to compete, we have an incentive to sabotage each other. Worse still, unlike in sports, we compete over finite resources (exit liquidity).

The biggest money-making edge on Polymarket nobody talks about: Private groups. Almost every consistently profitable trader I know is in one. I run a small Discord with sharp traders I trust. We share ALPHA and discuss markets, which gives us an edge against the average user.

🧠 Opinion & Narrative

• Should insider trading be allowed in prediction markets?

Gaeten Dugas@GaetenD

Should insider trading be allowed in prediction markets? I’m not referring to hard to find public info or paid subscription info, but rather private info that traders may have access to that the public does not.

• A reported Polymarket website glitch revives past criticism from traders

Ivan — Predictions & Current Events@IvanCryptoSlav

A good time to tap the sign that I warned about @Polymarket dumpster-diving two months ago. Incredibly, the site has managed to deteriorate even further with now recurring usability issues. Has mine and others' critique really "been heard"? https://t.co/hZvO2bGvS0

Rooke Brollins @RookeBrollins

So apparently the @Polymarket orderbook glitched, "crossed the spread" and brought the opposite side (I clicked Grizzlies, it gave me worthless Bucks shares instead, essentially taking 50k away from me out of thin air. This is absolutely not acceptable. @shayne_coplan
