An address in cryptocurrencies means a character set that consists of numbers and letters and most often its length is 34 characters (for example, Bitcoin addresses) and 42 characters (for example, Ethereum addresses). However, there are other addresses and other sizes... Address in the cryptocurrency is the address using which users can receive coins on their wallets as well as users can send coins to. In fact, this is the same as WMZ (WMB, WMX, etc.) wallets in WebMoney, 16-digit bank card number, phone number in Qiwi, etc.
