BTCUSD: historical view from 2013

Here a log plot of BTC since 2013.. do you see any pattern? :)
How to read this plot:
- Green lines are upward trends
- Blue lines are downward trends
- Dark violet lines are support levels.
Lines are in bold if they are strong supports for upwards/downwards etc.

Blue lines have similar slope... but shifted 3+ years.
Violet lines have more or less similar slope... but shifted 3+ years.

Here I am not predicting anything, I just want to provide my point of view of what happened to BTC in the past. I notice lots of similarities though...

All comments and feedbacks are welcome!
