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.
Basically when a person wants to invest or do business he must keep his extra money. Because many times in business there is more loss than profit then it can be restarted with extra money to compensate. Similarly, if a person wants to invest in Bitcoin, then he must keep extra money in hand and then join the investment. Otherwise, if he suffers losses by investing in Bitcoin, he will definitely break down mentally. So it's natural to keep extra money in any investment it's good for yourself. But there are some people who are new to start a business and must gain knowledge about it. And to invest in Bitcoin, one must start small and have special education about the Bitcoin market.
