During this period, exchanges typically organize events that can be rewarding if you know how to trade or identify promising projects for short-term price movements.
Just be careful with trading and new project. Do not let exchange reward to let you lose your money and yet not collect any reward. Just know that exchanges are using it to let people know about their exchanges. It favors the exchanges than the exchange customers. Even I have not seen anyone that have seen such reward before. If exchanges say they want to give $1 million. Be expecting $10 or less.
