I disagree with what you are saying here because in this crypto space knowledge is very much paramount, so if you have the knowledge and skills to flourish in the market, what makes you think that such person willing be at the losing end on the longer run?

Though it's a lot easier to buy an asset and hold, but not all asset guarantees success, it's only Bitcoin investment that guarantees such, the rest of other alt and shit coin alike can make you lose your hard earned money forever if you invested heavily on the wrong asset, so knowledge is the key thing here not by being a trader or an investor.
