Title: How to organize a (crowd) sale with ethereum! Post by: BrickShares on August 28, 2017, 04:19:16 PM I want to organize a crowdsale with ethereum with the next features:
-I want a very low minimum of coins to sell maybe just for 10ETH but i don't want the crowdsale to stop while 10ETH is reached what code can i use for this! So min 10 ETH and max 10.000 ETH -The crowdsale will take 30 days. The first 5 days 100% bonus but a min investment off 1 ETH, 6-10 days 75% bonus, 11-15 days 70% bonus, 16 to 20 days 65% bonus, 21 to 25 days 60% bonus 26 to 30 days 50% bonus! -all none solld coins will go back to the creator! - Is there anyway you can organize it like a normal sale so customer receives token and i receive the ether right away? -Is it smart to keep 51% of the tokens on another wallet so that nobody can hijack the project? -Is there a posibilty to airdrop a new coin under all holders of this coin in the future? Thanks a lot guys! Title: Re: How to organize a (crowd) sale with ethereum!
