I happen to have the opportunity to take basefexs $20 bonus. So far it looks good. The depth isnt as good as bitmex, but acceptable. I was able to withdraw the little profits I made from it. I currently plan to deposit a bit and open some larger positions.
As for the accusation, I want to stick to the facts.
1. Clearly something happened between basefex and bertyar88. It did not end well. Some FUD occurred on twitter and some influencers claim its basefexs fault.
2. Correct me if I am wrong but it seems among the ones who traded there, bertyar88 is the only one making scam accusation. All these influencers who seconded the accusation dont look like familiar with bitcoin futures trading at all - my apology if someone finds this offensive.
3. Both sides are capable of faking evidence. Telegram chat screenshots, withdraw history, and email records can all be easily forged these days with screenshot generation tools like this
https://fakedetail.com. You dont even need Photoshop.
4. Only basefex team and bertyar88 themselves know what actually happened. And both sides have the incentive to fabricate alternative narrative so they look like the good guy.
5. Basefex's trading interface is unique and tailor-made. Definitely not some quick imitation.
Scam is common in the world of crypto, as is extortion. I personally don't actually care whose fault it is. All I know is that basefex seems to be a legitimate alternative to bitmex so far in my own experience.
Just my 2 cents.
