this will be a difficult time for Biton to launch their ICO, the discount given is at most 20%, it looks like it's already quite a lot, but now ICO usually gives discounts of up to 50% at presale or private sale, so Biton has to work hard!!
to achieve their main goal of course they have to work hard!
Is it real that ICO gives discounts of up to 50% at pre-sale. Huge % usually don't give good result, it would bursts like a bubble
So you're right, the bigger the discounts, the more likely that the team wants to raise funds and just do nothing.
