If you're thinking history repeat itself that the price might crash like few years ago. I don't think it will happen again, btc is more popular now compared before. The number of user and investor has already grown up and keep on growing day by day.
Of which crash you are talking about? The crash of 2013 where we have crazy bubble caused by bot trading and speculative Chinese market with crazy margin trading?
This is not gonna happen again - if we will have next crash it will be either caused by legal issues - some kind of ban, or hard regulation on cryptocurrency.
Bad news - for example, another big exchange hack/crash or other bitcoin satellite service fail.
