There a lot of people who invest in bitcoin without knowing about its featues properly and later on they face a lot of difficulties. So, study before you invest.
Yes i totally agree with you jack.android, a lot of people hear about Bitcoin and then invest without knowing how it works Uptrend or Downtrend. After they loss money they say its a scam. But the truth is they know nothing about it.
People must always know how to learn and how to deal with problems that they might experience. Lots of people always say that business is a scam when they lose their money but the real problem is that they dont know how to handle things because they havent tried learning and knowing Bitcoin. Things that they can only so is to judge negatively without knowing the reason behind losing their fund.
