It's better to hold btc for a long period of time if it's price crashes.because we have seen btc to crash down from 900 to 400 worth of dollars and  over the night btc was able to regain it's value to 600 dollars.At 2018 now are we are talking about btc which is worth of 8000 dollars which also crashes down from 19499 dollars .So we can easily get an idea how big and strong btc investors are. So i am gonna hold for a long period of time if btc crashes down unexpectedly cause i believe there is nothing which can drag btc into the blackwhole.
