How have you noticed about that exchange? And how do you know you should ask about that exchange on this forum and on this section as well? Although their domain was registered in 2022, I wasn’t aware there is an exchange named BYDFi. That means they weren’t popular or newly launched.
However, it’s pretty sure you are shilling that exchange either on behalf of the team or you are its owner. But this isn’t the right approach to introduce any exchanges this way. The forum users usually ignore such shillings. It's centralized exchanges that are newly launched. Why should I choose it when I have well-known, reputed exchanges? I don’t even want to test it.
They may have bought an old expired domain to make people think that they've been around for years. In fact, a lot of new exchanges do that. Some even claim they've been around for years just so people trust them..
For me, the important things are that an exchange is licensed by trusted regulators, has Proof of Reserves, has an experienced team, and has a good reputation. It should also offer useful features, competitive fees, or good bonuses, along with responsive customer support that is willing to help users help them out.
Otherwise, using an unknown exchange simply because you came across a thread about it on this forum is a bad idea especially when it doesn't offer anything special that's worth the risk.
