It will be useful for reference if we actually can get the full brief of the research, the methods used in carrying out the research and how they came about the whole conclusion, otherwise I would just imagine that someone sat down in his bedroom, and out of reasoning and assumption, concluded that it is normal and believable that underdeveloped and developing countries are more prone to selling their tokens pretty fast than developed.

As long as there is no data backing it up, it is just a theory, not a fact! If OP is going to have to prove me otherwise, he sure knows he should be adding some link with detailed explanations of all I said initially.
