financial Spread-betting

I have heard much talk of spread-betting on the financial markets and was hoping the OG could enlighten me with info and experiences?

Similarly with penny shares, if anyone has advice or has traded in this way, I'd be very interested to find out what results came of it.

Thanks all!

well i havent done any of that but it is risky i would use money that you dont care if you lose it all. it is riskier than futures and options.
