Correct me if I wrong, but I saw an information that you pay your divideds in ETH. I see right now that the level of Etherium is 479,23 USD but a few month ago the lvl of ETH was 700 USD, are you sure that it will be better for you to connect your token AZ with this crypto currency and not with the FIAT money for example?
I guess that this is a question of price. Using fiat is not profitable. Or may be there are some other reasons why they use crypto...
But I have another question. If you use ethirium, there should be problems with my exchange wallet if I want to invest in your tokens, am I right? Or should I have some kind of software wallets that are connected with ethirium?
For ICO participation you should send your payments only from personal software or hardware wallets. It is not allowed to use any exchange services.
