Im not good at the maths How negativly correlated is bitcoin

Get daily average prices for both for the period you're interested in, create a dataset with two columns (variables) and correlate them with your preferred stats software

I'm bored so I just tried to get you an actual answer. I found that the BTC value has a 0.7506 correlation coefficient with SP500.

Data used:

SP500 weekly (ending Sunday) average prices for 2010-07-18 to 2016-07-03 from https://fred.stlouisfed .org/series/SP500/downloaddata

BTC weekly averages for the same period from https://www.quandl. com/data/BAVERAGE/USD-USD-BITCOIN-Weighted-Price

This is a very crude answer, however. You might want to learn maths/stats yourself.

So it would be a bad idea to diversify my sp500 index funds with bitcoin as a hedge?

I don't know, maybe. The correlation is very very different if you take other time periods. Also, you asked about negative correlation but I found a positive correlation in my example. Use the data I provided (or other data) and test a few things for yourself, you'll learn a lot.
