1) Invest only what you can afford to lose (this is crucial)
Should we have that on sticky?
+1. And this includes never borrow for investments (including credit cards). If you need to borrow it, it means you cannot afford to lose it.
Unless you know your horse will win
(Or put slightly different: Don't put more money into your
Cyprus bank account than you can afford to loose. When I had to sell and even had to add 5% commission in December, the guy I sold to asked me why I don't rather take a credit for my current needs and yes, I still consider that a risky thought as it would have put me into the position to have to put a "(virtual) stop loss order" on my bitcoins so I don't end up having actual dept which still can happen with a stop loss order when bitcoin goes worthless from now to then but then again, so can your Euro, too. Having dept in Euro is getting less and less frightening to me these days.
