While the breach/fraud/mix of both/whatever happened was basically out of your control (though should've been considered as a risk; paper wallets have been around as a much more secure storage mechanism for a while), a similar scenario could've occurred if Bitcoin crashed and you sold low, or if it crashed and never recovered.
I don't understand why someone would put 100% of something into a highly volatile and risky investment. Even if this were the ordinary stock market and it was 100% of your savings invested into one or two companies, it'd seem just as absurd.
