Political risk around national currencies can also affect the price of Bitcoin as people use it to hedge against price movements in a particular currency, or they need to quickly move large amounts of value out a country or currency.
Bitcoin is a decentralized currency and nothing can affect its price but only the supply and demand of it in the market. None of the government can affect it and none of the policy can affect it but when people afraid from these policies then they start selling their coins and the coin drop in market. If we will support it strongly then we will see a much bigger rise in the value of bitcoin.
