Great post! I do share most of your sentiments but I've been buying. I am about 10k STEEM away from Orca, which is my target. I will most likely never buy another STEEM beyond that. At that point I'll declare my STEEM 'Proof-Of-Brain' node is built, and I'll look for something else to build. Either way this goes, I am fine with it. As should any speculative investor, don't bet more than you can afford to lose. STEEM has a long way to go before it's an institution.
That being said, you are already investing time here and participating, so why not a little money too? STEEM needs more people like you with more stake to exert influence.
