If you say that bitcoin's 10k price is like an ICO's pricing stage, then does that mean that bitcoin will crash back down in the long term like how pretty much 99% of altcoins ICOs did? 🧐

techically every coin is ico and every stock is ipo. as far i undestood its just some coin has more support and bigger community and utility can go bigger and go longer.
This is quite correct. A coin having large community of users will be able to stand longer in this market than to those of the majority of ICO tokens wherein projects are temporarily active, which is the most observable difference of Bitcoin from ICOs. Community of users won't be enough, there is something in Bitcoin which keeps its market price, and that might be its reputation as a digital currency.
Just like what other users have mentioned, a better analogy would help. We do get the point. The market price of Bitcoin is volatile, given that companies are getting their interests into it, there is a tendency for the market price to increase eventually which would seem that the $10k usd, in this case, is an ICO price only due to the increase in demand. What made the analogy quite sketchy is the fact that what happens most of the time is that, after the ICO, the price of a token is on downfall direction which is somewhat in contrast with what is more likely to happen with Bitcoin's market value eventually. Still, the thought is there.
