Best Strategy to go in this kind of scenario - 20% on first five days and 80% throughout the year . For example if i want to allocate 1 BTC of my portfolio to EOS , i am planning to invest 0.2 BTC in first five days offering and rest of the 0.8 BTC i would be allocating/investing throughout the year. I feel this is the best and safest strategy for a honest ICO!
