I strongly agree on your opinion that, the current decline of bitcoin and other altcoins could be attributed to so many factors and one cannot be optimistic on when the decline will stop though some speculators are of the believe that the market has reach the minimum bottom and we should expect an upward trend soon. And adding also my opinion that, just keep buying if you still have the financial muscles to invest, After all you are helping your own course. And demand is low now this the reason why price keeps sinking. It takes people like you to increase the demand for bitcoin. In addition, one thing i can tell is that bitcoin is here to stay for a longer period of time, i am not talking about the alt coins, i wonder what all coins will be active a few years from now and we may not see all the coins that are created in five years time.
