Instability here is another thing in the crypto currency , a person can earn excellent profits in an hour but also a lot to lose for example half of the Deposit for the fact that he could not sell and get out of the coins or the project in time.
Right, the market is too volatile to expect anything but high risk and high probability of losing your investment any time. What bugs me personally is the bounties that don't pay up after 3-6 months.
