I think the point here is not which one has larger applicability, but which is the usage in real life. Most of steem transactions represents actions made on steemit. From monetary point of view is irrelevant, but from technical point of view it proves the superiority of Steem and of DPOS consensus algorithm. From usage point of view, is a some sort of currency which is heavily used.
Otherwise, I agree that they share the same differences between a bank and a social network. To some point we can compare them...
Yeah Isee what you're saying, steem as a platform, with the user count growing and the interactions growing exponentially shows amazing potential and power of the algorithm, but it is limited to Steemit and a few other marketplaces whereas bitcoin is becoming ubiquitous. Also, I think the usage case is hard to put a value on, because there are so many bots and spammers now just putting up a few lines trying to be rewarded. More isn't always better
But it proves that @dan's next project EOS will work and handle a heavy load of transactions. EOS has a future as a very robust distributed application platform.
The point @jerrybanfield is making is, it's early days for Steemit/Steem. Bitcoin started in 2009, Steemit in 2016. That's a seven year head start. Perhaps, Steemit/Steem will make it big, perhaps not. BUT if it does...
