What was the bonus for presale investors? And what the difference between presale and main sale? Im just new to crypto world and do not understand much
This is so easy. Presale is taking place much earlier that main sale, the project is not well advertised at that time, but youll get large bonus for investing. For example, additional 50%. At the main sale stage the bonus decrease. I hope I helped you in understanding the principles of token sale.

You are absolutely right, but presale of ATF has ended long time ago. What I dont get, is what the bonus at the ICO stage? How will it decrease?
