I will create a smart contract. The project is on the TestNet. Token is ERC20 Ethereum token.
I am testing a crowdsale with discount.
Token name is TestXY (TXY)
Normal price rate 100 TXY = 1 ETH
There are 3 different groups on Crowdsale. Group A, Group B, Group C
Group A - %15 discount - 1 ETH = 115 TXY
Group B - %10 discount - 1 ETH = 110 TXY
Group C - %5 discount - 1 ETH = 105 TX
Non Group A,B,C investors - 1 ETH = 100 TX
Each groups have 100 Ethereum Addresses.
And some more details I will tell on chat.
