There is no normal being that loves getting losses on business, career, investment and trades that's why even company holders make financial policies to keep record of investment and profits flows. And unlike other business bitcoin also makes sales and losses if you do not investment wisely....is nice when you put in what can not put you sickbed or gives you hypertension, don't invest out of what you cannot withstand the loss.
Is better to use small money or learn risk management first before investing especially newbies.
That's why most people always say that only invest what you canafford to lose, don't invest that you will regret in the end. So if you're just a beginner, the suggested thing you should buy Bitcoin and hold it for a few years, don't do short trading in bitcoin right away without knowing or having any idea about it. It's okay to buy Bitcoin while you're learning it as long as you hold in long-term.
