The chart is from early March 2019 (see https://howmuch.net/articles/investing-100-at-IPO). According to their methodology description, prices were taken as of 15/02/2019, when BTC was 3.593$. All values have logically shifted, but BTC is now at around 6.918$ (92,54% higher), so that would drive total value on the chart from 7.186.980 $ to 13.836.000$ … a minor correction …


Note: You should be able to post the image. Imgur is fine. Image file size (actual file, not dimensions) needs to be below 2.5 Mb.
In any case, this is a very reduced (just to show you) view of the image in the author’s article referenced above. Once you post it in the OP I will delete mine.
