@sames You should be careful what network you're referring to. They all vary in terms of security, robustness and governance. To say Steem is better than Bitcoin is too easy. Steem is v. different. Bitcoin is a network for transacting that is incredibly decentralised and beyond anyone's influence. This is why it's the biggest.
Steem may be quick, but Steemit inc is still holding much of the reins. With a complex social media blockchain like Steem, this is necessary, because it's not just about money, but it's providing a service.
But it means that Bitcoin has a bigger chance of replacing a bank than Steem, because Steemit , inc still has a lot of influence on the token and its value.
Same goes for Ripple. It would need to step far back from XRP. Right now it's too involved.
They argue that Bitcoin is controlled by miners. But at least with miners they are incentivised to secure the network... for now. It's very different to having one company incentivised to secure a network.
