Honestly If anyone just come into crypto space through a link or online ads it's easier to get lost and fall victim to scams, i never get hacked for once or lost money to scam projects simply because I favoured learning things I don't know anything about, why can't people be like this either? This will easily safe you from money doubling schemes and Ponzi schemes, please newcomers and members, be more willing to learn.
A wise man said, "scientia potentia est" which is a Latin aphorism meaning "knowledge is power" (Francis Bacon). Indeed knowledge is power, that is to say, you need to learn in order to have power over what you want because it is through learning that you will understand how best to guide yourself. You have clearly distinguished it all, most people failed to understand that lies in the crypto space and that's the reason why most always fell for scams, hacks or makes mistakes like losing their keys etc. Therefore I agree with you, until we start learning what is obtainable here, we might keep falling for the wrong things such Ponzi etc.
