I invited my brother (@atis94) to the Steem/Hive blockchain five years ago (in 2018). He registered his Steem/Hive account on 2018.01.23. He used the platform for a short time, and then he left. Yesterday (on 2022.11.26) we talked about it, and he did not saved his password, so he cannot even login to that account anymore. Probably many people lost the access to their Steem/Hive accounts this way.
hmm, yeah.. true that.
At least he didn't lose any funds there, he still has an ongoing STEEM delegation coming in.
How much time did you burn to try to get him into the action?
Not much. He registered relatively quickly. But he also left the platform very quickly. He have not used the platform since then.
