For me I would recommend you to buy but it still depends whether you started before or just started this moment. Of you just started this moment, I definitely recommend you to buy now because this is an optimal starting point considering bitcoin is starting to rise from its downfall.
Buying is the actual decision that should be made but still if someone is unable to convince himself for any further investment, he must hold on his coin for at least a year. This will not only help him in gaining some good profits but he will also discover the details about his coin and nature of digital market which plays a significant role in success of any investor. This is the last chance of increasing coin amount.
