I do not think investers are stupid like you think, because they put their money. Also, you can see easily smart contract address which token is related. By simple search in etherscan, you can see it is not Viberate. It has different logo, either. People has announced and everybody said not to confuse Vib with Vibe before.
Vibe took over 15m $ cap in presale and has now daily 70-80k $ volume. Most of us is waiting and believing project. Increasing of coin value is, i think, related that in presale, chinese and USA citizen was not welcomed because of terms and regulation. Opening a market has provided this rule to leave behind. I believe in this project and when it is listed in decent market, it will be enter in first 100 icos at coinmarketcap.
