Investing without knowledge and understanding of financial and market cryptocurrency is failing to be understandable. I've become accustomed to a lot of people who invest in this market because they find that others are profitable without any knowledge of cryptocurrency. Be serious with your investment and invest only when you really understand the market.
Agree with you, that is why before you enter in one thing we should need to study first how it will works but there are some or many people who are very greedy to earn money without knowing the risk they have, crypto currency is not promising source of income but you can earn by putting some effort in some earning method avoid greediness to avoid loses.
