This well argued article suggests the source of the original news about china outlawing all cryptocurrencies and exchanges is often quite reliable with past government actions occurring within days of this news source breaking the rumour/ news.

I no longer know what to think but if the interest of bringing you balanced views here is the article arguing the ban is real (as earlier I published one saying I thought on balance it probably was fake news having witnessed quite a few fake news leaks in the year or so that I've been amateurishly investing small amounts in crypto)
