It's the first time I hear about this particular case. The site of the old Estonian exchange is still live, but it's no longer operational. The man moved to The Netherlands and started the same type of exchange there and called it CoinEra. https://coinera.eu/. That site is also still live but non-operational just like the Estonian version. He did write an announcement when he closed it down mentioning he never experienced the issues from Estonia in the Netherlands.

Interesting case. Estonia has lately often been tagged as one of the most crypto-friendly nations in the world. Looks like that wasn't always the case. Probably the root problem was that the government wanted to tax the traders but Otto didn't make it easy for them.
