I'd say to you all: get used to bombshells dropping! At some point the investor pyramid scheme will go crashing down. It might be now. All those companies were on borrowed time.

The honeymoon's over, investors want to see ROI.

I mean this cycle will probably recover in a few years when the markets recover but still - some lessons stick
