I also think that 10,000 Satoshi is a very small amount to register on the exchange. I would have thought of other ways to encourage new users on the spot of the exchange.
Well, on other exchanges do not give anything for registration. Let's say this is not an incentive to register, but rather as a nice bonus. You can buy some tokens of young and promising projects for the money and who knows what amount will be in a year!
Yes, but why hand out this small amount? For the user, it does not matter, and the exchange loses a lot of money if it becomes massive.
