I have a small thing to know and I hope that you will be kind enough help me to settle this matter. I read the things in the links that you sent me and I want to know a little thing about the map given in below link which you given.

https://bitcoinist.com/11-countries-bitcoin-still-illegal/

There are some countries marked as "no information" in the map. If the local authorities of that kind of country also have no clear idea about cryptocurrencies, will it be a problem to trading the cryptocurrencies? How can take a idea weather the trading cryptocurrency is legal or illegal when the local authorities also haven't clear idea about it?

Please help me to take some idea about this matter.
Thank you
