From what I can see, they're just reminding people that bitcoin is 'not legal tender' in Taiwan just like everywhere. Now whether this implies illegality, or a ban, depends on where you live I suppose but I doubt they'll be shutting down any Taiwanese exchanges.Headlines like this have the potential to scare away investors, though.
Last time I checked, they are not illegal in any way, but they reminded they financial institutions to be cautious of bitcoin and crypto's in general. And did you know that there's a Bitcoin ATM in Taiwan?
https://bitcointalk.org/index.php?topic=2422999.0The presence of bitcoin ATM is a clear sign that bitcoin is not illegal there. And remember that Taiwan-China relationship is very rocky. So I conclude that what decision mainland China does, Taiwan will not follow, on the contrary, they will do the opposite. Like China has put a crackdown on bitcoin, but Taiwan still remains a bitcoin friendly nation.
Thanks for posting this topic that I started a month ago, I was about to post the picture.
Well, i'll post it here again anyway:

I was very surprised to see this ATM while waiting for my egg roll to be cooked

and could not help taking a picture. Then I got some information and there are actually 5 ATM In Taiwan.
There is also Maicoin >
https://www.maicoin.com/en if you look closely you can see the icon picture of HI-LIFE which every Taiwanese know, this is a convenience store similar to Seven Eleven.
Looking good, I am happy to live there even though I don't speak yet the language very well.
