China have destroy bitcoin and make all of mining bitcoin project at their country have closed, many ICO investment was die by China have banned of regulation for ico investment at their country, China have more power fo destroy how bitcoin price.
l dont think china have the full power to destroy bitcoin yet despite their population are so much involve in bitcoin mining and other cryptocurrency activities in the crypto space .the cryptocurrency is not control by any Government . the china Government can only cripple altcoins that are built on the soil of china who founders and team are residence or citizen of china . those ICO that die most are scam and not genuine intention of entering the crypto market most of them dont even have directions of what they intend to achieve. there are ICO that are still doing well irrespective of the previous china banned.
