# Python for Finance Code Repo 11.2

Could someone please comment the answer for this question please? There’s a character limit for this post so I’ll use the comment section for space please check :) Let's continue with our Bitcoin calculations. You decide to invest \$1000 in Bitcoin in 2018, at the price in the declared array: \$3869.47. 1. Calculate how much your investment is worth at the end of each year using the prices denoted in the code. 2. Draw a chart to showcase how much your \$1000 investment changes in value each year.

First, calculate how many Bitcoins you will have at the start by dividing your investment by the cost of Bitcoin in the first year (the first element of the given array). Then multiply the entire array of the prices by that number to get the value for each year. Use np.multiply(array, number) to multiply an array with a number.

Don't forget to import the matplotlib.pyplot package under the name "plt" to draw the chart using plt.plot() function. Add the plt.savefig() function (using the name of the chart as an argument) at the end of the code to draw the chart in the CodePlayground.

There’s a code someone posted on the ‘Code’ section but it doesn’t work. Below is the code that someone posted. https://code.sololearn.com/cv335YU63k18/?ref=app

I think this one is correct. https://code.sololearn.com/cv335YU63k18/?ref=app but on the line 13, it should be np.multiply not np.mulitply
