To raise $$$ millions by selling people 100 million coins created out of thin air! Lets hope dear sasha atleast put some good buy walls up so ICO buyers can escape with their original amount before he cashes out!
Firstly it is a method of fundraising so let's not pretend this is some hidden secret motive.
Secondly WAVES is the currency used to protect their network in a PoS scheme.
Thirdly it is used to process transactions.
It may also have implications in applying the AML/KYC strategy per account.
There may be many other reasons as-well such as collaboration with strategic partners using WAVES.
Don't be fools.
