Yeah looks like someone bought around 50-100 BTC worth and that's it. Then some scalpers tried to provide support, ran out of buyers and price dropped again. However I think the original purchase which was all committed in under an hour was a genuine buy. So its someone who really believes in this project.
No need to use large fonts. Just use the command line. Go and google "ethereum geth commands" and make your transactions using the terminal. Its usually much more stable and you won't get these GUI issues.
