Some say BTC is digital GOLD. And that is value in and of itself if enough people believe it and place value on it.
In practice, there is no place to spend your STEEMs you earn on steemit, other than to cash out to some other currency that has value to trade or use for purchases.
So I'm not sure I buy your argument as valid rational for STEEM to be more valuable than BTC.
Exactly my point, steem is not the same as Bitcoin. On a lighter note you cannot use gold to make any purchases unless you're a government.
You need steem to have visibility on this site and make money... the more steem you have, the more you earn, it is the only coin out there that do this, social media have the potential to reach more people than BTC... The only reason BTC is the most expensive coin (and profitable, by now) is because its the first, but technically it is the worst crypto-currency out there (slow transactions, high fees), once crypto gets enough popularity things will change...
Soon or later we will be able to buy on many online stores with steem and many other altcoins, just like you can buy anything with BTC on purse.io...
