SCAM

The UMA resolution can be easily influenced by people with a lot of tokens, so the outcomes do not rely on truth, but rather which side has more money put in.

Dodgy

Some day a whistleblower will spill all to a journalist and we'll hear all the dirt, but for now it's obvious that UMA and Polymarket can't be trusted to tell you the weather yet alone to trust with your money.

They are running a massive scam scheme

They have manipulated markets that were more than obvious. There are whales with 6M UMA that decide 35% of a vote. This means even a couple whales can join and decide a market regardless if their decision is correct or not. Further more these whales bribe polymarket employes to change rules in the middle of a market. UMA also deletes messages and bans people who disagree with the whales. I got banned for 7 days for not agreeing white their decision

Whales manuplated the outcome

will-edgex-launch-a-token-in-2025?

Was a big scam, the obvious result was NO but UMA and Polymarket whales changed the results to YES

Very big scam and I know a lawsuit will follow as its obvious manuplation and insider manipulation.very obvious and SEC and other countries should follow suit to ban this scam company.

I am reporting to SEC and EU authorities too

UMA is a scam OWNED by polymarket

UMA is a CENTRALIZED platform OWNED BY polymarket, and that will do whatever their owners tell them to. Look onto the 'USA UKRAINE MINERALS DEAL POLYMARKET SCANDAL' which resulted in the scam and theft of over 7 million dollars

If I could give a negative review I…

If I could give a negative review I would. UMA is supposed to be a independent decentralized project made for resolving bets (particularly on poly market). In theory (emphasis on „theory“) they would resolve based off of facts. This is not what they do. They make decisions off of the voting stake (backed by buyable tokens). Basically no matter what it is you could just buy „votes“. Currently in the „Thailand bombs Cambodia by Friday“ bet the „NO“ betters (ones who voted it wouldn’t happen) currently have amble evidence showing there was no bombing yet the „YES“ betters (ones who voted that there would be bombing) are winning (have won) for the reasoning that „whales“ with hundreds of thousands of dollars bought out the market. Push for the death of UMA. I hope they get sued and those on the side of truth get the shares they deserve.

Not decentralised nor honest

It claims to be a decentralised oracle, but 2 people hold near 40% of the UMA tokens with different wallets. It's very easy for them to bet on anything and then push for that outcome even against clear visual evidence and facts.

Don't be surprised if at some point UMA token holders will tell you the Earth is a cube.

THIS WHOLE UMA SYSTEM'S CORRUPT

THIS WHOLE UMA SYSTEM IS BUILT ON A 100% CHANCE OF GETTING SCAMMED. IMAGINE LETTING PEOPLE WHO HOLD THE MOST UMA SHARES CONTROL HOW A VOTE GOES WITH 0 REGARD TO REAL WORLD FACTS. BE AWARE OF IT & STAY AWAY FROM ANYTHING THIS SYSTEM IS INVOLVED IN!

Not impartial, money oriented.

UMA Is the platform used on Polymarket for solving all disputes.
Proof in internal chats demonstrate that the votes are associated to tokens.
Math is very simple here, the more tokens, the more influential the vote will be. The majority receive a share, making the vote completely manipulated by money volume instead of sources or facts. Doesn't sound very decentralised,right?

These are the real scammers

These are the real scammers! The decision in favor of YES or NO is not determined by an honest vote, but by a few large holders of UMA protocol. Deliberate market manipulation. Do not contact them under any circumstances or you will lose all your money.
