BNB vs Polkadot
BNB (BNB) and Polkadot (DOT) both sit in the l1 platforms category, so they compete for the same slot in a portfolio. BNB launched in 2017, 3 years before Polkadot. BNB uses Proof of Staked Authority and Polkadot uses Nominated Proof of Stake. This page compares what can actually be verified about each protocol — nobody can tell you which will be worth more, and this page does not try to.
Cryptocurrencies are a highly volatile asset class without the protections of regulated funds: you can lose your entire investment. This comparison is educational content about the technical characteristics of two protocols, not a buy recommendation or a price forecast.

Frequently asked questions
What is the difference between BNB and Polkadot?+
BNB (BNB) launched in 2017, uses Proof of Staked Authority and has a maximum supply of ~200M. Polkadot (DOT) launched in 2020, uses Nominated Proof of Stake and has a maximum supply of ∞. Beyond the numbers, they were built for different purposes — see the description of each below.
Which one will be worth more?+
Nobody knows, and anyone telling you otherwise is guessing. Crypto prices depend on adoption, regulation, liquidity and sentiment, none of which can be forecast from a protocol's specs. This page deliberately compares only what is verifiable today.
Which has the scarcer supply?+
BNB has a hard cap (~200M) while Polkadot does not (∞). A cap limits future issuance, though it tells you nothing about demand.
Do they use the same technology?+
No: BNB uses Proof of Staked Authority and Polkadot uses Nominated Proof of Stake. The consensus mechanism affects energy use, how the network is secured and how new coins enter circulation.
Should I hold both?+
That is a question about your risk tolerance, not about these two protocols. Crypto is a volatile asset class where you can lose your entire investment, and holding two coins in the same category adds far less diversification than it looks — they tend to move together.
