Recently I encountered one "amazing phenomenon".
In the Trezor Suit app, I wanted to create a new BTC-address, but I couldn't do it, because the new segwit address was the 11th in a row (i.e. 10 addresses had already been created before). This application issued a message that the limit for creating addresses (of this type) was exceeded. The rest can be created (for example, legacy and other).
It's called an HD feature. (Hierarchical Deterministic) Wallet. Literally almost every wallet you find now are HD wallets. They work by hashing your seed phrase to get a master private key and a master public key . Now this master key can be further hashed to get child keys and the corresponding addresses to those child keys come from the hashing of the public keys.
