Wow, are there still people who believe in that bitcoin will crash at some point? And if bitcoin crashes, the other altcoins will be much more stronger as what they are right now.
Maybe at the beggining a lot of people are going to be worried about that, but at some point, everything needs to move forward, if bitcoin crashes, another altcoin will replace it.
And no, i am not worried about that, and for those who are saying that bitcoin will crash, i guess that you did not even bought a single fraction of bitcoin on your whole lifes.
