This is interesting for learning purposes, but I wouldn't recommend anyone following your footsteps.
If you would to buy Bitcoins in July 15th and hold them until August 15th (you mentioned mid July to mid August in your post), you would have made 88.3% (from $1978 to $4151).
It would be interesting to see how your portfolio does over the next months (if you intend to keep it and update us) while comparing it to just holding Bitcoin.
