would you open a loan to buy the dip? and when it dips again you would open up another loan to buy the dip. and lets say repeat the process. probably no one is doing this. because being in debt is a bad thing. just depends on far u would invest into bitcoin or even crypto currency. sad it has to dip in the first place.
However attractive to buy a coin in this situation, you should not, remember to invest only what you can afford to lose, you can end up losing everything and in big debt, if you make a loan to buy this dip because there is no guaranty when will the market rise again.
