For those saying to simply 'reduce your investment if you don't like the risk' - that isn't the answer either - if I've invested a certain amount of BTC on just-dice then I am expecting to make a certain amount per day on average and that amount is directly proportional to the amount I've invested - reducing my investment reduces my profit but keeps my risk exactly the same.
Does not compute. Please explain why your risk stays the same when reducing your investment.
Risk of loss of a certain percentage of my investment in JD. Not risk of loss of my total amount of bitcoin asset including that not invested. I suppose it's dependent on your definition of risk.
