Telegram ICO is definitely a scam.But the platform it has provided currently helping lots and lots of new comers who is either investing first time or who is unaware about various process to participate of ICO,Its official communications etc......There are always 2 sides of every good work,one side is good and other side is bad.

One way telegram is helping all ICO investors by immediately replying to investors queries and other way scammers are active scamming new bees.
but one thing i wanted to say loud and clear is that crypto world itself is full of uncertainties and people whoever coming here to make money should know this world first before stepping in.

Learn telegram how it works,learn how ICOs works and then invest,you may not succeed initially but you will not get caught by those scammers.
