What does "Fourfold increase" mean?
eg: This November 11th they spent a staggering 19 billion yuan on Alibaba’s online platforms—a fourfold increase on a year ago, and more than double what Americans spent online last Cyber Monday.
Does "Fourfold increase" mean increase by 3 times or 4 times here?

"Fourfold" means increase by four times. It ALWAYS means that, wherever you see it. So here there was a fourfold increase to 19 billion yuan from last year. So last year there was 19/4 = 4.75 billion yuan spent on the online platforms.
Mr X: "We sold 10 million pounds worth of computers this year but we want to increase that fourfold next year".
Mr Y: "Ah, so you believe you can sell 40 million pounds worth of computers next year then?"
Mr X: "Absolutely. It will be hard but we can do it!"
Hope this helps and take care

Whenever we say X times increase over previous year, we mean to say that This year = 4 times last year = (last year) + 3 * (Last year)
So the increase in absolute terms is 3 times and the final value is 4 times the last year.
X = Last Christmas = 4.75 Billion
4X this christmas = 19 Billion
The increase = 19-4.75 = 14.25 = 3 times 4.75
0
fourfold = four times
