I've participated in so many bounty campaigns and invested on some tokens coming from ICO, but I notice that so many of these projects are not or stopped updating their Bitcointalk announcement thread but they are so active in their telegram channel.
Do you think this is good for a project in general, let's admit it, Bitcointalk topics always shows up in search engine like Google while on telegram you have to scroll a lot or wait for an answer and they are missing up some potential investors who first look on Bitcointalk for project that they want to invest in..
Maybe they move on to other platform or maybe other people are right that they really did run away with the money of the investors. If there's still activity in their accounts in other platforms like social media or their website, you do not need to worry. But if there's no other platform that they can update or announce stuff, you might as well be scammed. This is the downside of this industry, many can wear a mask and pretend they're your friends but that act can also happen in real life with fiat. Scam or not, there is always a risk in investing and not everyone can conquer it.
