Dont look at even lower price to buy cheap, this is cheap enough, but dont spend all your liquid cash right away either.
I expect both sides possibility at this juncture. The price are sliding downwards for bitcoin and many fiat markets. It is also not a bad decision to wait it out before buying or selling. Patience can often help in the market.
This is of course just a thought, I agree with you and I believe that bitcoin should be going up anytime now, anyone who isn't sure about what's going on, could just wait and see the price going up and will be too late. I know that it isn't a healthy situation to be in right now, but that isn't a problem and we should be quite proud to be here when it's so low, and will be proudly saying we bought it at 30k, when the price hits 100k+ in the future.
