Do you mean that they are not interested in creating a telegram group for their project or that you cannot visit the group. There should be a group that can ask about things that many people who wish to participate don't understand.
It's not me who can't access the group, but indeed there is no telegram discussion group, they only provide email for us to ask questions.
Wow, it's so interesting that a project doesn't have a group to calmly discuss ongoing projects and ask things that people don't understand about the project.
Good project will have telegram group after ICO now, its not like 2017-2018. Look at another project telegram. New bounty uunter askin on telegram channel. Yelling and screaming about airdrop while many people put moneybon project and stay quite.
Better to have telegram group after ICO done.
