Do you accept buyers from every country?
Probably people from China and the USA are forbidden to join, because ICOs are banned in these countries.
yeap, youre right
maybe you guys know how to avoid this restriction?
There is no way
You have to attach documents to buy tokens (id and address)
Its possible only if you have dual citizenship, i think...or if you falsify you documents
I would never give my personal information to complete strangers, who may be some scam people...They could easily take a bank loan pretending to be me or something like this
Yess...I suppose in our days of scams we need a KYD (Know Your Developer) procedure...
Don't agree with you guyys. KYC procedure is necessary for all the business whether it is connected to the blockchain technology or it is related to any other business. It's collected for the business owners security and other information purposes.
He is of course right with his suggestion but to be honest KYD is already there. If you don't support a project where the developer isn't known, KYD will naturally come into existence!

Your fault if you trust anon people.
I don't understand how KYC helps developers to resolve safety issues . How will they understand that particular man participates in ICO, he could send another person's identity documents for example
