1. Mining pools in China constitute 70% of all pools in the world.
10. 64% of Bitcoins are never used and will never be used.
18. 17 million Bitcoins is expected to be used in about 10 years.
40. About 17 million Bitcoins is expected to be used in about 7 years.
1.mining pools are more spread out. take antpool which loads say is "china" fact is they have farms in georgia san fran, iceland.
as for other pools, some are actually in thailand, russia, and other places. seems geography is not OP's strong suit
(you can spot this as antpool uses a separate coin reward address for each facility. if you actually add up the asics and the facilities of their locations. you will see "china" doesnt have as much as you think
10. over 70% of coins
moved in the last 2 years (might be worth the OP doing fact checking)
18. & 40 they counter each others points and only 40 is the closest answer.
