RE: Is Steem the most popular Crypto today in terms of real users making transactions on the network?
Unfortunately, no more. Arguably it used to be when there were more active users and other chains have just begun to develop dapps.
Sadly Steem has not made full use of the headstart and is falling behind in terms of awareness and technical performance. More people know about Tron and EOS than they do Steem.
There is much to be done to bring steem back into the limelight, while efforts will be herculean, it is not impossible.
