I will continue to believe in bitcoin even if bitcoin will not have an high value like nowadays.
Just because it's a big innovation (like Internet!) and can create a new way to share economic benefit to all people and not only a group of bankers.
How can you say that bitcoin do not have a high value nowadays! do you remember the start of this year? the price was half of what is today and now it is increasing much more and in the coming future it will double up once again.
