For some time ago I had problem with the chart, it didn't sum up my holdings correctly.
After a while I realized that the missing coins in the graph hadn't any visible percentage calculation in the holding tab/screen. By removing and re-adding these posts the graph shown correct value.
Hope this help others with similar problem.
PS. Blockfolio team, it would be nice if you could update the app with
SEQ and
DYN icons. Please shout out if you need the icons in a specific format or resolution.
