There is a problem with blockchain apps at the moment, you have to pay to try a lot of them out. Take cryptokitties for example. You need to buy a kitten and pay a fee to send the coins needed. I do not want to pay to see if it works and that is the same for cars, or planets or whatever item you want to use. These sites are not scams but that entry point really is a big deal. And if it is part of a social media site it is an even bigger deal.
We are just starting with dapps and, as expected with any new tech, people are going to be suspicious to try them. I don't blame them, I am the same way. There are a few I passed by because I didn't want to send the coin or buy the coin. I just want to sign on and play or post. And if I like it maybe I will buy some of the coin.
And that is the biggest advantage of steem. You want to try it out, its free. You want to send steem? Free. Post? Free. You get the point. The site is free to use for anyone. You can buy guys if you want more voting power but if not you can still use the site and make the coin. It is this free model that is a huge advantage to this site and it is this model that is needed if crypto is going to go mainstream.
