I previously registered to BitYard and recently discovered that it is now BYDFi, and that it's their 3rd Anniversary! However, as I am not a big fan of centralized exchanges, I decided to make my own analysis to check if it is worth it, and overall if it is a reliable exchange:

• BYDFi user interface is similar to Binance, what allows to quickly and easily use it.
• There are some tasks for new users allowing to earn up to $2888 in rewards.
• The markets page highlights Bitcoin (BTC), Ethereum (ETH) and some other altcoins like EPX or NWC currently. That's a good way to differentiate from Binance.
• BYDFi fees are as follows: withdrawal fee 6 USDT (0.0002 BTC), taker fee 0.3%, maker fee 0.3%; whereas Binance fees are: withdrawal fee 0.0002 BTC, taker fee 0.1%, maker fee 0.1%.
• One advantage of BYDFi over Binance is that Copy trading is proposed directly, whereas to make Copy trading on Binance you have to go through their partners.
• Now, regarding the security of your funds, BYDFi is headquartered in Singapore, and they have licenses from the US and Canada for their derivatives trading platform. According to Cryptorank, their Proof-of-Reserves is not available. However, we can also note that they have partnered with Vibranium Audits to work on these topics.

In summary, BYDFi is an interesting alternative to Binance, with a similar user interface. Although their fees are higher, they offer some advantages, like Copy trading, directly available from the user interface without having to use a third party partner like on Binance.
