I suppose that new users will understand that it is necessary to buy SP obligatorily when they see that they cannot publish and comment on everything they want from the beginning. A little guidance is also necessary as then you will not see any gain in investing time in the platform initially.

Perhaps introducing them to the different Steemit communities and DApps, could attract a little attention and even commitment. It is also important to make known a little about the world of blockchain and cryptocurrencies.

Once they fall in love with Steemit, I think they themselves will invest more in STEEM. Because it is not the fact of buying them but of keeping them that allows the stability and liquidity of the cryptocurrency. 

Remember that blockchain technology is continually evolving as it is disruptive. I'm sure STEEM's blockchain has barely grasped its usefulness. Once we understand that, the possibilities are infinitely positive and profitable.
