Defi has clearly only a future, where fees are low (because it's impossible to use for Ethereum now), transactions are fast (because people don't want to wait) and Defi needs to be censorship resistant (to be a truly Decentralized Finance).
For Ethereum, it's decentralized and fast but not cheap, for Binance, it's fast and cheap but not decentralized.
My most favorite Defi platform is Avalanche [AVAX]. At Avalanche, Defi is cheap, fast and decentralized. It will really have a great future and bring us a much more better Defi network.
