If bitcoin prolly gets to 100k dollars,will it still remain a legal tender?

It's only a legal tender in El Salvador so I don't know what you're talking about bitcoin reaching that price and remaining a legal tender when it's not a legal tender in majority of countries.

correct, only El Salvador adopt bitcoin and used it as a legal teder on their country , wherein no more other countries because of some reasons and i hope you know what it is..  
And base in your question @trojane, well yes 100k  is not possible because indeed the amount of bitcoin adoption is continually increasing every year , but when it comes to become legal tender after achieving that value, "if that's what you trying to say" ., perhaps we still have no idea.. Because bitcoin still have problems reasons government don't like it ever since before.

I think if governments wanted to stop the momentum of Bitcoin they would have banned Bitcoin already. They have not reaching $100k will not change their minds on banning it. We will see more taxes I think but Bitcoin should remain legal to use and trade.

No matter how huge the rise of Bitcoin is, it will still be buyable, because no matter how high the price goes, you can always buy BTC depending on how much you'll spend your budget for it, again, it'll just become much more expensive since the price goes up, @mk4 answered all of your questions and I'm just here to drop my two cents about Bitcoin's price going up to a point that it cannot be bought.

I think like you but I do think that Bitcoin will be harder to buy without KYC in the future because the governments will tighten their restrictions and regulations.
