one theory i have as to what's contributing to this is the fact that the returns on safer investment alternatives are so low. example, savings accounts that earn 0.5% annually. i remember when i could easily get 6%. so now taking a risk and spreading a large gob of cash across say 20 startups looks more appealing because even if the overall return for the group is a mere 5% that's much better than <=1%
