Even with all those potential markets, you'd have to look at the success of each.
As a social blogging platform, are more readers and writers attaching and staying?
As a potential ebay-replacement, would development time that direction be worthwhile? Does it need decentralization?
As a bank and financial instrument, how good of a role would it play? Would people really save money in Steem Power, given its volatility in the crypto market place? Even with 2% APY, I can't trust that the value will be higher or lower when I need the currency.
And lastly, all of this requires liquidity. To spend Steem or SBD still requires a pretty rigorous process that limits mass acceptance for now. This problem is pretty crucial to success in the various marketplaces.
And to caveat, I'm actually long and bullish on Steem, but I know there is room for improvement .
Thanks for the great writeup.
You bring up a plethora of relative points. If/when Steem is able to be exchanged directly for fiat will be the determining factor in allowing Steem to reach it's full potential of every day usefulness. If/when this would occur you would eventually see Steem debit cards like the Bitpay card for BTC. This factor I feel is the most important factor along with Steem continuing to build it's user base. Great comment.
