Tenured, great post.
This is the bitcoin trust board. Bitcoin is extremely volatile as we have experienced.
I didn't quite get in at $300 bitcoin price like you did but I was helping some very wealthy investors mine bitcoin at that price. I was the tech guy setting up and running the machines (bitcoin price ranged from $200 - $400 during that time). Unfortunately, I didn't get in on the investment side myself till mid 2017. Been mining and acquiring ever since.
I am playing the long game here until I see a change of course for Bitcoin (and about 10 alt coins).
At best, I would put bitcoin in the second inning of a 9 inning baseball game. But due to the recent mass adoption by Wall Street, we may have just started this game.
Good luck all
