One other thing that is causing this is they want to earn big whereby they wouldn't know which is really, they can keep holding for years but when scammers shoot in they wouldn't know that is a scam attempt that is why it's good to always join a like-minded people around you to share common knowledge and ideas together to know when such attempts is approaching or are wanting to come near you.
Investment involves being wise and becoming smart in everything they are doing to avoid being scammed.
Factual...some people just think maybe once you wake up you start making it in life, not knowing that you have to work for it in a smarter way. It's better we seek good knowledge from different sets of experienced members to achieve a common goal. Although some people's lives are full of risks, some risks may end up in scamming. Always have knowledge of what you want to do and learn from good examples. Invest in what you know that in the future you will rejoice, not regret.
There are many investments, such as physical investments; examples are oil, agricultural products and gold,you can also invest in real estate, depending, but in my own belief cryptocurrency is the best investment ever; being a crypto investor makes you a boss. So knowledge is very necessary,indeed Bitcoin will continue to make our dreams possible.
