I will talk about Japan.
I had been receive the same questions over and over again for mosaic things.
Is a mosaic of NEM attached with images? And Why is not a mosaic of NEM imaged?
In Japan, tokens (= mosaic) are almost all those who think that it is natural for images to be attached.
This is because CounterParty (https://counterwallet.io/) with XCP as the basic currency is so penetrated.
For use of CounterParty, the token issuer will pay with XCP, but general users will use BTC as a commission for receiving and sending tokens.
There are also things that can be freely painted on tokens, which is also a strong motivation to publish oneself.
In addition, a token holder can distribute BTC, other tokens etc proportional to the amount of possession of tokens to those who have their token.
There are also services (https://tokentalk.org/) where other services are also entering and secret articles can be read by holding a certain number of tokens issued using CounterParty There is.
This is one example of usage of the most successful token (= mosaic) at the moment.
The wallet application is also substantial, and it can be used merely as a BTC wallet.
The first stage is a coin-type token that has become popular, even until the real exchange. I also have over 100 kinds of tokens.
Recently it has become common to be sold as games, collections, idle cards of TV programs, and distributed. For example:
Furthermore, I drop tokens on the map and there are things like Pokemon GO.
The token is falling on the map of Tokyo central city. BTC can also be dropped.
How far is the official mosaic of NEM? Or 3rd-party will make it, I can not predict that around.
However, in Japan, because it is a function that is commonly used, I think whether it is easy to realize if it is NEM.
Thanks
