I know this has happened to some people
They wanted to post their address into some block explorer but copy paste still had a private key
Another day they log in and poof all the btc is gone
stay safe my friends!!
Did this happen to you? My goodness! If this happened to you, I hope the wallet you are using is only having some small amount of Bitcoin. Because if the amount is somewhere around 5 BTC, then mistakes sometimes really pay a high price.
Take very extra careful next time.
