As I am a stock market investor, I would suggest you invest in stocks rather than bitcoins. The main reason is that firstly, bitcoin is a virtual currency with no physical existence and secondly, one cannot predict the market movement when it comes to cryptocurrency. Recently, in the month of June, we came across news Bitcoin Crashes By ~24% Post Outage In The Cryptocurrency Market (You can read complete news here: https://kalkinemedia.com/2019/06/28/bitcoin-crashes-by-24-post-outage-in-the-cryptocurrency-market/)  which was a huge loss in the cryptocurrency market.  Thirdly, it is not at all supported by any of the governments globally. Once any government initiates the step for bitcoin legalization then we can think of investing in it with safe and secure results.
Whereas in stock markets you can at least study the market flow and invest accordingly depending upon the news. So it is much safer to invest in the stock market.
