even if you're spending more time on research regarding a specific altcoin or ICOs but scam and fake ICOs are too good to be true.
the only way to not get scammed is to wait for them to appear on coinmaketcap.com or crypto exchanges so that will ensure that they're not scam or fraud.
you can do research about ICOs and altcoins but nothing's safer when you do hi invest on crypto exchanges especially if their trading volume is consistent and higher than $50,000 daily.
