The golden rule is and has always been, "only invest what you can afford to lose." That way, whatever happens you don't need to get stressed. Life is short and we really shouldn't worry about little things like shitcoins. Better to be safe and just invest in blue chips like bitcoin or ethereum.
You can handle your coins or manage your emotions, if you invest make sure you will not put all your savings in one game if you loss, you lose some hows your emotions if it is happen try to manage your emotions and be wise.
