Being relatively new to Hive and Hive-engine I too had a similar experience when logging into Hove-engine for the first time. Suddenly I noticed I had tokens that I had accumulated( maybe carried over from steem) that’s when I thought, what if they are worth more in Hive than I actually had in my account. Anyways further investigation proved they are worth sweet nothing but it just goes to show how many people could be sat on a bigger pot and not know.
Good post and something worth looking further into I feel.
