For long term - yes
For short term - no
Bitcoin is likely to crash in coming days when people will start dumping their coins and that will create panic in market so if you are looking for short term gains then better to wait for next couple of days and see how price behaves and if it falls then you can buy it at much cheaper price.
The market to me is not really showing a lot of panic so far. We cannot ascertain where the chart leads but from what I can see from previous corrections and now, things are getting different. I cannot say much about coming days, but when it does, and then you should see a lot of traders buying in pretty fast.
Everyone expects the Bitcoin price to fall soon. I also thought that will happen when it reached $10k, but now I changed my mind. I think it's just the beginning of the bubble and we have huge growth ahead of us. So my answer is yes - it's worth buying a BTC for $ 10k
Beginning of which bubble ? You call that a bubble? Well, it is your opinion and bubbles burst, whereas little corrections like this which you yourself stated it that a lot of people thinking this is a bubble are feeling it would even go lower than this and now the value is just busy hovering around $14,000 - $15,000. That shows some strength which a bubble cannot have.
