Bitcoin still worth to buy and right now, the price is on the lower rate so you can use this chance to buy more bitcoin. The investor was buying bitcoin on the low price because they don't want to miss a good opportunity with this. I am sure that if we can purchase bitcoin at the lower price, then we can have a chance to sell bitcoin when the price increase and it increase. Besides that, in this few months, I see that bitcoin still doing right movements because the price still up and down in this range of the price so I guess that we can make a nice profit from trading.
