Money is indeed a basic thing but it is not a contributing factor to why there is such a huge difference between US and Chinese gains.
Is it not a contributing factor? It's the main contributing factor!
If you don't have the money you don't have bitcoin! END of the story, there is no magical device that costs zero and gives you bitcoin.
You need money to invest and the more money you have the more investment you can make.
Stop being surprised by this, it's not a matter of GDP it's a matter of purchasing power in $, and although China had almost all of the advantages with exchanges located there and people buying when prices were low, with mining farms, with mining gear manufactures it can't simply offset the balance, especially when for years Coinbase alone held more than 1 million coins in custody!
I strongly agree with this. Most of the Indian cryptocurrency users have been driven underground due to harassment from the authorities. The registered exchanges such as WazirX and ZebPay have around 5 million users, but if you add those who mostly depend upon P2P platforms and foreign exchanges, then the number may easily cross 25 million.
And if their average investment is 10$ they will not have even 1% of what Micro owns right now. Besides those numbers have been exposed so many times when we talked about volume in those exchanges, it's fake it's worse than okchina or huobi in 2013. Those exchanges you claim have 5 million users, Coinbase has 50 million, 10 times more users with 20 times more income per capita! Can you call this competition?
