Investing 100% of savings

Hi all, relatively new to the cryptocurrency world and just started reading more about it. I have a hypothetical scenario - let's say you had a steady income and reliable career outlook - no concerns about job stability for at least the next decade.

Also, let's say you don't plan to have children or make any large puchases (like buying a house) for the next rew years. How would you feel about investing all of your savings (after paying for all necessary living expenses) for about five years into Bitcoin - understanding that it will fluctuate during that time but that eventually its value should increase? Would there be any reason to be concerned about big institutions manipulating the market in favor of traditional equities and thus needing to diversify? Or should we remain confident that Bitcoin is here to stay for the long term? Appreciate your opinions
