If you spend your bitcoins now, you might regret it soon. The selling has been non-stop since reaching $13,000 and it seems that the market is very oversold, yet no sign of stopping. However, if you spend it now, maybe next week or the week before that, the price may gain 50%.
You can spend your Bitcoin now if you really need it specially if it's an emergency needs however it's not how it should be spent. Although keeping it can benefit you whenever it gains value to the market, it doesn't guarantee a sure profit thus it's still a gamble in my opnion. Keeping Bitcoin should be a spare money thus you can benefit from its ups and downs.
i am not sure if it is wise action to put all fund you have in bitcoin.
since you are mentioning that "in case emergency , you can spend it"
if you only put the free money in bitcoin , there is nothing called "in case emergency scenario" , you will just holding your bitcoin as long as possible and about spending bitcoin , you can exchange your fiat directly to bitcoin and spend it directly too. pretty simple right?
i can not see any disadvantage by holding bitcoin for long time if only you really know the risk and really know the money you put in there as something that othing to lose but a really long term investment.
spend bitcoin anytime , hold it all the time.
