It doesn't matter if I am holding bitcoin or not, it matters what I support. I support bitcoin because of its technology and the features it provides. Nothing in the world will not replace bitcoin.
It is hard to predict what will happend in the future. For the bitcoin holders, they investee in bitcoin it means that they believe and support it so it is impossible for them to betray bitcoin. We dont want to waste of time to betray as we start to take a risk and brave enough to trust cryptocurrency.
