Price rise and price fall will always be a part of bitcoin journey, if price falls you should not get panic and have faith that it will rise again in future.
No it isnt and price doesnt really determine the value of the investment. Once the world realize that bitcoin is far more than pump and dump stuff, we will be able to purchase things by using it and I mean alot of things rather than just some niche which means the price wont be any significant factor to worry about anymore
