Trolls like to make comments like "How will you look your family in the eyes when you have to tell them you lost all our money when Bitcoin crashed."
Well, it is a good question, isn't it? How will you?
You should definitely think about it before putting all your savings into bitcoin. It is the wise investors, not the trolls, who say "don't invest what you cannot afford to lose."
They don't want that type of comment applied to them. "How will you look your family in the eyes and tell them you knew about Bitcoins when they were worth under $1000, now that they are worth $100k. We could have been set for life, and not left with all this worthless fiat".
I have let pass countless opportunities when I could have multiplied our money by 10x, yet still have no problem looking my family in the eyes. Perhaps because there were also many "opportunities" when I could have lost it all, and there was no way to tell which was which beforehand. I could have bought WorldCom or OGX shares a year after the IPO and sold them at the top. Or could have bought them a coupl of years later, and been unable to sell before they crashed to zero.
