like any economic market, there will be ups and downs. the thing you gotta ask yourself is "do i think that crypto currency is going away?" for me, the answer is no. There is no question that this is only the beginning. best thing to do is take advantage of the downturn and invest! Probably the reason it's down is that a lot of "get rich quick" people have taken big chunks of money out of the market and spent it on dumb shit instead of using it wisely
