Should I do a remote investment with or without a LLC?

[Vidit S.]

Hoping I can solicit some knowledge from the experienced community here once again. 

What I understand from my nascent research is that one should ideally form a legal entity (LLC etc) to buy any investments to protect personal assets from any lawsuits but I am curious how many actually do that because it comes with an added overhead. I have been reading BP forums a lot lately and noticed some people buy investments directly under their name instead of creating an LLC especially if they are doing a remote investments.

Is that just a lack of knowledge on their part or it is an educated decision? If latter, then what is the reasoning?
