I wouldn't say it is tied up to gender; it is related more to the knowledge that a person has related to BTC itself and the current market.
Both can have shaky hands due to not knowing how things usually go.
Then this statement could raise another question, why do women have less knowledge or interest in Cryptocurrency? The only good and rationale answer that comes to my mind is that men are generally more of a risk-taker than women, we could associate it with the fact that there are more males in extreme sports. Men are said to love the adrenaline and the rush in doing risk-taking activity. Therefore, in term of investment, women tend to choose what they thought as a safer option such as stockmarket.
Also the fact that men are seen as supposed to be a provider in our society generally, cause men to have more responsibility and cost to pay in order to provide, making them to take another approach in making more money including risk-taking job and Cryptocurrency, forcing them to see a better opportunity within risk.
