Well you have quite a teetering point of view I've not heard recently. While scale capacity seems to be the primary criticism in regards to what qualifys as a viable economic platform. Bitcoin itself is held up entirely through public opinion on it's value. I think the values they promote and promise are the most significant in their evaluation since as you stated the software needs to improve.
You are obviously using the steem blockchain so you must consider it reasonable. If Bitcoin and Eth fail as you suggest they will cause the whole crypto market to collapse. Steem is unlikely to survive if reduced below a dollar per steem.
What alternatives would you suggest?
