I think slightly yes,people will show up a lose interest when it comes bitcoin will died,but i highly believe bitcoin will not going to die,it will more stronger and powerful crypto currencies in the whole world.
People will only lose interest if bitcoin will die, but as it is very difficult that bitcoin will completly become dead, it will only be the increasing interest of the people in bitcoin. therefore i think that people are not gong to lose interest in bitcoin but their interest will continue increasing and bitcon will surely become more and more stronger.
