Spot on and I don't think that will ever change, it's why I see bitcoin as becoming more in line with gold that is spendable. It won't be used as a daily currency but more for one off purchases etc. Unless the price was relatively stable this will always be the case.
The article is actually stating the truth. Bitcoin is not what it was meant to be by the original vision. The current fluctuations are currently only profit opportunity and the stable Bitcoin is far away.
I don't know if we will ever see the Bitcoin becoming the stable currency used by all. For that to happen value must jump even more but the current progress on the market isn't promising.
Holding is actually recommended but for the Bitcoin core, it is actually destroying it for a long term.
