If bitcoin will fall maybe these coins will give you your money back, because always when bitcoin is falling altcoins will rise up. This is happening nearly always so you can expect it.
Dogecoin that its a jokecoin has also rise a now bit thanks that bitcoin is now falling.
Simple if the BTC falls albeit slightly then the ALT rises,it's often the case that you are right now ALT is moving forward but I think it will not last long.See all ALT simultaneously move up as now there is only 1 possibility of whale being on ALT is quite profitable to sell now even though only a little profit.
