Introduction

We have a bounty of 1 bitcoin, split up in 10 chunks of 0.1 bitcoin.

How does it work?

In 10 dates between 2010 (included) and 2019 (included) we have taken 1 bubble out of the picture.
Your goal is to find the dates that are missing a bubble. Each date with a missing bubble will earn the finder 0.1 BTC.
Bubbles have been taken either from the top or the bottom sections, never from the middle.
Quite simple, really.

How do I qualify?

To qualify you need to:

• own the date with the missing bubble you're reporting
• show us how you calculated you have the right date (telling us you think you have a date with a missing bubble is not enough)
• like and retweet this tweet
• follow @drngart on Twitter
