I certainly do not recommend buying Bitcoin in large quantities, because I've experienced it, it has negatively impacted my social life, so I started to stress. Stress is very damaging to human life .
It's almost impossible to buy bitcoins and don't get worried and stressed by those fluctuations, rumors and forks.
Besides that, you could get a little paranoid with the security. So, i agree with you, invest large amounts can be harmful to your emotional stability
