In my opinion, as long as it's new, very hard to tell if it is safe to invest. You have to observe and analyze the coin's fluctuation on the market, then make a decision to minimize the risk.
Just be careful with any platform that provide attractive deal or huge profit, they might be a scammer (not all of them).
I'm new to this, can you recommend me some reliable platforms or wallets?
I recommend to you to use Binance launchpad, OKEx, Houbi (at least those platforms will safe your money) to participate in new project.
I doubt to ICO project since you are a newbie to this field, unless you have got more understanding to make an analyst against it.
