Some countries don't allow people to invest in ICOs. Why is that? They don't allow ICO that issues dividends and represents the shares of a company, or they just ban all the ICOs?
It's just a rule. Laws are everywhere and it's just how countries want to run their country. Some countries seem to think that all ICOS are scams and wil ljust take away from people's savings, others justify their actions from labelling ICOs as unregulated securities, there's a bunch of reasons.
It depends on the country. Some countries ban ICOs outright, some just ban the purchasing.
If you aren't in the listed accepted countries it's better to stay away from any ICOs.
