Sadly a lot of these scams are in countries that don't have an regulations so its pretty easy for most scammers to get away without any sort of punishment.
Yeah that's true...investors should also be upgraded and never invest in a project that has no ICO reviews from those ICO rating sites. That was I noticed those with no reviews are higher chances of a scam project. Better to research first on yourself before investing. It's difficult to punish a scammer in crypto and no one had been jailed.
