Higher number if Telegram subscribers doesn't necessarily mean that the ICO ROI will be higher. Any channel can get more number of subscribers by advertising it on social media and various forums. So it dose not mean that every person will be investing in their ICO. There will be hardly a few members who will be willing to invest in their ICO .
I believe advertising on various platforms might, running campaigns can gain attention towards the ICO. A good project will definitely gain more followers if they workout in their project accordingly.
