I think you are right mostly, I do think Steem will continue to grow and will be here for a long time, it does have a lot of problems, the ones you mentioned are a few of these, awful posts with a lot of votes, being trade able on only a few platforms etc. still I think these problems can be overcome. That being said I do think you should take out some of what you have made, it took you a lot of effort to get there, might as well enjoy it.
