There's been a lot of hype surrounding Polkadot these days. The alternative smart contract platform is definitely faster and cheaper to use than Ethereum itself. It's already within the top ranks in market cap. Yet, people have forgotten about Binance Smart Chain these days. This smart contract platform is as cheap and fast as Polkadot (someone correct me if I'm wrong), serving as a great alternative to the Ethereum blockchain. What these platforms lack is a solid number of dApps to overcome Ethereum. There doesn't seem to be any indication that developers are going to build new and exciting dApps on both chains. As long as Ethereum has the most dApps and tokens, its rivals won't be able to stand a chance against it.
Now the question is, which of the aforementioned platforms is better? AFAIK, Binance Smart Chain (powered by BNB) has a greater level of centralization than Polkadot itself. This should make the latter platform a much better choice for everyday people. Still, there's potential for BNB as it could attract businesses and companies in the mainstream world. Which will survive in the long run, is an excellent question. Thoughts?

Of course, the polkadot has been showing itself very well lately - people have long wanted a new, technological and working platform! But still, it has not yet been tested by time as binance, which has shown the most stable work over the years, and their token is only growing in price and breaking through a new ATH level!
