At that point I go this question in mind ;what does it really take to become a Bitcoin investor .does it mean that if you own a considerable amount of Bitcoin in your wallet you are now a Bitcoin investor or there is more to it aside having a basic knowledge of crypto currencies
To become a bitcoin investor you must have money and knowledge as the main requirements, because if you don't have money you definitely can't afford bitcoin. Talking about money, of course many people have it, but also many of them are not investors in bitcoin, so money and knowledge are equally important to make anyone a bitcoin investor. Investors must also understand how to store bitcoin in a safe place, this is no less important than money and knowledge about bitcoin.
Your friend is new to bitcoins so you can advise on how to store bitcoins in a safer place, as security and risk are a concern. After everything is understood, let him continue to be consistent in investing so that one day he becomes a successful bitcoin investor.
