Regarding your first point above, sometimes you may not realize that something is an issue until someone else raises it, and a lot of us are juggling a variety of things, so I think that in the end, you handled it well.. and sometimes preemptively striking is too much.

Regarding your second point above, even though arguably we have had various periods of lower levels of bitcoin price volatility, it really seems that bitcoin is going to remain considerably volatile for several more years into the future, and so various individual investors in bitcoin need to consider these volatility matters in order to better protect their own investment in BTC, which is maybe a bit more work than some people want to employ to buy on the way down and to sell on the way up...   

A bitcoin investor does not need to trade in really high quantities in order to achieve some BTC portfolio protections by buying on the way down and selling on the way up.

There are a couple of ways to lessen concerns about bitcoin volatility:
        1) your bitcoin portfolio moves so far into the green that it does not really matter so much to you if BTC prices change by 10 or 20% or even more.  Personally, I still believe that these kinds of BTC investors can still profit from BTC trading, but I recognize that it is less of a concern when most if not all of the investment is pure profits. 

        2) the market cap of BTC rises to such a degree that manipulation and volatility becomes much more costly to achieve.  This is almost so far into the future that we cannot quite imagine it.  I personally believe we need at minimum about 100x increase in the market cap, but 1000x would be quite a bit safer in terms of lessening bitcoin's volatility.  Yeah, sure I could be wrong, and possibly we could achieve 100x in a couple of years.. though I am thinking 4 years or more would be more likely - if it does occur (I hope to be wrong about my 100x BTC timeline idea, here).
