We can see it decline, but what you need to do is look at the big picture for a while. Bitcoin has gained thousands of USD in value this year, even if it goes down by $2k it will close the year with twice the price it had last year! Show me an investment that doubles its value in a year. Would you consider something like that a bad investment?
That's how Bitcoin works. For each 1$ you pay for it in a year or 2 you'll get 2 or 3. It's possible that it will go up by 4 or 5 and then fall back to 2, but you will still be making money, so stop with that negativity.
