There had been several projects that turn to Binance chain in the past but they are just the ones who wanted to be listed on the main Binance.com exchange. Now they are nowhere to be found.
Exactly. It's no wonder why Binance Chain is able to provide extremely low fees and blazing-fast transactions to its users. The utterly-centralized design of Binance's own blockchain network makes this possible. That's why most projects have been built on Ethereum. Competing chains are nowhere near close to Ethereum in terms of decentralization, security, and reliability. The only exception is ADA. Yet, the slow development progress from the team has left Cardano behind Ethereum in every way. The world's second-largest cryptocurrency by market cap has been able to retain its popularity in the mainstream world, even with the ridiculously high fees and slow transaction confirmation times. It'll be hard (if not impossible) to take it down anytime soon.
Nonetheless, high fees on the ETH blockchain makes "De-Fi" impractical to the average person. Competing chains like TRON, EOS, Binance Chain, and Polkadot have a huge advantage over Ethereum with their low fees. If developers would've made the same number of dApps on competing chains, it would've been possible to challenge Ethereum in the long run. But the lack of a solid ecosystem on alternative smart contract platforms, forces people to use Ethereum in order to interact with their favorite decentralized apps. If this keeps up, Ethereum could become a "monopoly" in the decentralized crypto/Blockchain space. At least, upcoming ETH upgrades will alleviate the high fee issue for a while. But we need an ample variety of dApps on other smart contract platforms in order to ramp up the competition. People could exploit "De-Fi's" true potential using a platform that's economically viable for day-to-day payments. Time will tell us what will lie ahead with "De-Fi's" prominence in the mainstream world. Just my opinion
