Bitcoin is better owned for our future plans. Because bitcoin a great option to invest for people who are keen to see opportunities. Very loss if we have bitcoin just for things that are not useful, example "gamble for fun".
Sure, if when trade Bitcoin/Altcoins and not focus on it, you will loss very more your money or can loss all if you not take loss!
But only invest Bitcoin, I not think you can loss your money, unless you sell it when you see the price of Bitcoin down more the price you buy
