I think before investing you should know the benefits and know the loss of bitcoin before you invest in bitcoin, bitcoin can provide a lot of benefits when bitcoin prices rise, while you can lose when the price drops.
How would you know your profit and your loss when you will be just investing on it for the first time? You can't just know that before hand, if you want to invest on Bitcoin, the advantages are it's anonymity and it's volatility though volatility is an advantage, it is also a disadvantage so whenever you are investing, you must also know that you will either lose or gain profit.
