just be patient and wait to rise again as it will probably go up again, but when it comes down it's a chance to buy bitcoin at a price down or cheap and buy as much as possible if it is able to buy lots and hold it .. because your chances to sell it in the price rises or fits as expected, because the development of bitcoin is very good and always increases. but still do patiently do not be too hasty so it is not slah to take decisions and learn first before acting in order to get a big profit ..
