I know we're back in a bull market because I'm getting daily pitchdecks again asking for angel investment. This time I won't be making the same mistake of investing just because other people I know are investing. Because most other people are idiots. And I say this as an idiot myself.

So what will be my new filter for investing in a startup? 1) I actually understand how it works. 2) It has generated revenue. Anything. 3) Valuation is under $10,000,000. Otherwise I'll keep putting my money on Bitcoin and not waste time.
