I've never understood why we tell newbies, or anyone else for that matter, to only check a few characters of an address. Checking a few characters is not a foolproof way to protect against clipboard malware now, and it will become even less reliable as time goes on, malware becomes more complex, and vanity address generators become more efficient.
It is not time wasting to check all characters of an address. If I withdraw my Bitcoin from exchanges, I would like to check it two or three times, depend on each exchange confirmation process for withdrawal.
- 30 seconds for one checking time.
- 1 min 30 seconds for three checking times.
- It is worth to make sure I don't make any mistake for my withdrawal.
How to lose your Bitcoins with CTRL-C CTRL-V (LoyceV)
Since my first transaction through bitcoin blockchain, I always checked every number and letter that I copy pasted to the receiving address text bar, I am doing this because I'm afraid to lose the funds if it there were some mistakes I've accidentally input. That thread that you've mentioned just made me check the address even more.
It's never a waste of time to recheck the address, I have a friend who laughs at me when I'm checking every single text in the receiving address.
