Fine post with excellent perspective and some pertinent points. (And written in wonderfully blunt and direct text, which provides a nice personal touch. :-)
We can add that the minor dips and peaks make absolutely no difference for long-term investing. Several times over the past few years, bitcoin has plummeted over 50%. I bought in 2 spurts, both times when the price was dropping. After my purchases, the price continued dropping, and stayed low for relatively long periods. Today, those historical drops are completely irrelevant.
The same goes for other cryptos, and in fact, the same goes for those stocks that are now at insane levels. Apple, Amazon, Google, and many other non-bluechip stocks went through similar trajectories to those that cryptos are going through now.
(For steem and bitcoin, the outlook is much more positive than for the aforementioned stocks. While those stocks are now insanely overvalued, it's safe to say that most cryptos are still insanely UNDERvalued.)
Given my experience with bitcoin, I intend to buy more steem if and when it drops to 70 or below. And if the price hovers around that level for a year or more, I'll grab another armful.
To summarize this long comment: Buy.
Totally agree... the buy and HODL method for Steem :)
