I know that Taproot addresses are starting with bc1p, and Native Sewgit addresses start with bc1q.
Letter q is the bech32 encoding of the number 0 that should be witness version 0, but this can change in some future version updates.
Check out BIP 173 encoding table below:
https://github.com/bitcoin/bips/blob/master/bip-0173.mediawiki#bech32
Topic: Do all Native Segwit addresses begin with bc1q? - page 2. (Read 317 times)
1. What is the significance of the "q", and why that character?
The 4th character refer to witness version, where "q" is witness version 0.
2. If the "q" is the standard or a must, how do you explain this Binance support article that talks about Segwit addresses? In the screenshot, you can see that the address on Binance begins with "bc16". The info in the article may not be completely correct, but the screenshot is surely not a mistake.
Must be typo, "6" refer to witness version 26. See table on section Bech32 (https://github.com/bitcoin/bips/blob/master/bip-0173.mediawiki#bech32).
1. What is the significance of the "q", and why that character?
I don't know. But I've always wondered why they use "bcq1" and not just "b" if it's always the same anyway. It would reduce the address size by 3 characters.(updated until blockchair_bitcoin_outputs_20211202)

We often hear how Native Segwit addresses begin with "bc1", but the 4th character in a Bech32 is also interesting. It is always a "q". At least I though that it was always a "q". If you look up transactions in recent blocks, for example, you will notice that the "q" seems to always be the 4th character (unless it's a Taproot address).
I have three questions:
1. What is the significance of the "q", and why that character?
2. If the "q" is the standard or a must, how do you explain this Binance support article that talks about Segwit addresses? In the screenshot, you can see that the address on Binance begins with "bc16". The info in the article may not be completely correct, but the screenshot is surely not a mistake.
3. Are there Native Segwit addresses that don't begin with "bc1q" (like the one above), or is a mistake of some kind?
I tried scanning the above address with Electrum on my mobile and the app is importing an Ethereum address. It might be possible that they did that on purpose for whatever reason. Maybe to prevent people from sending coins to it and then blaming Binance for their mistakes.
