I think that we should invest only such amount in bitcoins, which we can easily afford to lose. Risk is always present in all investments, but I want to advise you to invest in the long term.
I completely agree with you. It is important to watch yourself to avoid being reckless. Personally, I think it is bad to put all your money and commit them into multiple investments. It may be better if you put only a fraction of your money so you could still have some for yourself.
