The best way when sending someone your bitcoin wallet address is to copy and paste it, but most mistake newbies make is trying to type a bitcoin wallet address which sometimes may not be exactly the same and correct because of its mixture of both lower and upper case alphanumeric letters, especially the P2PKH, P2SH and Bech32 wallet addresses and may lead to lost of fund.
It's indeed advanceable to copy paste addresses, then double-check.
However, the statement about "
most mistake by newbies" leading to loss of funds due to typo error as the isn't correct.
Because there's a "
checksum" in addresses whether it's P2PKH, P2SH or Bech32, so if at least one character is typed incorrectly, the user wont be able to click send at all,
unless the wallet is poorly designed or the person is just extremely unlucky that he typo~ed a valid address.
BTW, Bech32 can only be either all upper-case or all lower-case characters, not mixed.
