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...
