Still on my rookie journey and this is a bit embarrassing, especially from an accountant.
A while ago I wanted to buy some ETH . The price was around 0.104xxx, which really meant little to me. As a prudent investor, I figured I should bid at 98xxxx so I punched in my bid price. Normally after I hit complete, a small screen flashes up and says my order is being processed. This time a second screen flashed up immediately and said my order is completed. I panicked and quickly checked my order. I had punched in 0.98xxxx instead of 0.098xxx!!!
Soon we will call you the ETH whale! Say 1 satoshi and all is forgiven.
