What are the Functions of Scalability in Crypto?

In early 2017, I sent BTC from my wallet to a crypto exchange, but it was delayed or unconfirmed for seven days, I realized the density of transaction traffic on the blockchain network at that time and of course the transaction costs also increased.

So basically crypto scalability refers to the ability of the blockchain network to handle transactions quickly, cheaply and securely. So what do you think are the functions of scalability in crypto?

Scalability allows blockchain networks to handle more transactions per second, increasing the system's capacity.

In reality, scalability not only refers to the blockchain's ability to process transactions but also to improve security and decentralization, accelerate transaction confirmations, and so on.
