In my experience bitcoin always rise and has great potential than other crypto currencies. I suggest you to buy now because whenever bitcoin fall it will increase high. I myself buy more coins and holding them. Bitcoin never Disappoint you nor you feel regret for your self. But do not turn your all money in bitcoin just invest low and watch the price. After few weeks, you can invest more. Do not invest for days do it for months. Buy it now and forget about your money in bitcoin wallet.
