I think KYC is normal for joining any project.
For the minimum investing. I think it's for presale. I dont see any minimum budget mentioned in public sale (ICO)
I asked the admin on the telegram and they said there would not be any limit in the ICO. But I have trouble with the airdrop. I do the daily task yesterday and now I see the status "not complete" in my task. They said that they will check again
I'm afraid that they will forget, many projects have so forgotten to support the user. This is a good project and is about to be completed, quite a pity if I lose the EXC bonus.
