Bitcoin and alt currencies are risky investments as a whole. Never invest what you are not willing to lose. You have no idea how much I lost in the stock market during the banking fiasco that closed several banks a few years ago.

This technology is in it's infancy and subject to new hack / attack techniques on a daily basis. Hell, even micro$soft has it's regular patch Tuesdays to mitigate such things. And I believe their crew and resources may be slightly higher than Coinex.pw or ANY other exchange out there right now.
