I disagree with you that Bitcoin is overvalued, but I would rather say that it's expensive at the current price. Being expensive doesn't mean it can't move higher, or doesn't have the right to, so let's be guided.
Also, I don't see how Bitcoin would hit $10,000 as you predicted anymore. Go through its history, and you would realise that it has not been hitting 10% of its ATH in recent history, let alone 1%.
Aside from the history, Bitcoin's price is being solidified with diehard investors' funds and those of institutional investors. These alone should stabilise the price above $10,000.
