Is there a minimum contribution or can I buy for like 0.5 ETH?

I have bought one of the first TimeMints with the minimum contribution of 1 ETH. I thought it would be a good idea to get one early and jumped in without much research. I thought I can sell it later or buy some more DAY in the ICO so I can use my chronopower which should be close to 1%. Now I am not sure if this was a good decision getting the Timemint, you can only sell TimeMint when you have 8888 DAY Tokens, I won't ever get that much. And I won't see much growth with my initial 24 DAY so I probably gonna need to add more when they show to have value.

My Question is: What would prevent me from selling my eth wallet with private key so another person can use the TimeMint? ? I am excited to see where this project is heading too, but I am a bit worried too as I haven't seen any confirmation that I got a Timemint or even contributed, hope this will follow soon.

Hello coss.io team. Your project seems promising and legit, I am about to invest some ETH into it. I read much positive stuff while researching and I believe it is a good investment opportunity. But I also stumbled someScam accusation, they seem strange to me, I found them on a random blog and also on medium.com . Probably just some wrong accusations from competitors, but I still wanted to know what you say about it as it held me back entering the token swap atleast for the moment. https://medium.com/@blockchainalart/coss-io-ico-scam-update-92f5788e9efe and https://www.blogpays.com/2017/08/09/coss-io-ico-scam-alart/

Hope you can explain me where this come from so I can join the tokenswap while its still at 8% bonus. Thank you, I wish you good luck with coss.io
