Of course they will be friendly because their so called "brothers" took a step backward towards bitcoin. But we like what we are hearing from the government. If they remain friendly then we will see them as another force to reckon in the Asia region with Japan and South Korea. And maybe this could also have a political effect. The Mainlanders will definitely go there because we all know that the Chinese bitcoin community is one of the largest if not the largest active bitcoin community in terms of investing in ICO and trading before the unfaithful decision of their government. This is huge for the ecosystem, if hundreds of Chinese investors and traders suddenly flock to Taiwan and do their bitcoin activity there.
I've said it many times when people were asking "what if the world bans BTC?" The world never acts as one body, when some people see failure or threat others see an opportunity. If one country starts banning BTC another one will come up with a way to profit from it. China and Japan were great examples of this, up until today when I've read about Taiwan. They are producing so much electronics that if they started following Japan in their attitude towards BTC we could have another huge boom.
