My question is can you or anyone else give me their best argument as to why the bottom is in or not.
From my perspective, your question is
inappropriate useless.
Bitcoin is a new emerging asset class, in the initial throes of price discovery. To attempt to time this market is madness.
Price goes up; price goes down - you can't explain that. All we really know is:
1) whether or not the world knows it or not, it needs a permissionless uncensorable form of money free from the whims of central planners; and
2) a vanishingly small percentage of the world has yet awaken to postulate 1).
From these two, we can conclude that the long term trend is up, and will remain so until such time that the world at large is onboard.
Ignore the noise. Buy today all you can conceivably afford to lose. Hodl on.
