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.
Because investing is long-term, and during the period of time we are waiting for the investment to grow and benefit us before we take that benefit, many things can happen to us so that when investing not with spare money then when something urgent happens it is very possible for us to sell the investment, and the worse things selling when there is no growth or even when there is a loss, so actually investing is not an easy thing, it requires careful planning and good calculations, but investing is highly recommended because it is a way to make us have assets that increase in value.
