Investing in bitcoin will always be his/her own decision because, it his own money that will be use to invest or to buy it. However, it is not wrong to listen to other's opinion to make necessary and effective decision on whether to pursue of to invest. It is also necessary to make the research or study before engaging in any transaction. Right now, on my opinion is the best time to buy and then hold a bitcoin until the price increases again. Believe that patience is a virtue that will earn a reward in the end.
