NFT investor made a $1M mistake by accidentally listing a Ether Rock for 444 WEI instead of 444 ETH! 
This is just one example why in order to gain mass adoption in the blockchain space the technology needs to be more user friendly.
Myself I been in crypto since 2018 and to this day every time I’m moving a large amount of crypto this is me until I see it show up in my wallet.
Haha! So true. I still have panics thinking i’ve made a mistake even after double and treble checking before i hit confirm.
Ive used Proton XPR a few times and that is so much easier as you send to an @username instead of a long random alphanumeric addy.
you might have to school me. I can’t take the anxiety no more! 
Brutal. Crypto is sometimes. One slip up and you can lose everything. Scammers and bots everywhere waiting for that momentary lapse of judgement.
Totally, Ive seen some very smart and aware people fall victim so it can happen to any of us. You need to be on the ball 24/7 as like you say it just takes one moment of not thinking and it’s gone.
