Too bad bro. You should only gamble what you can really afford to lose. It's been said all of this time almost everywhere when someone sees who did it wrongly with their supposedly long term savings. You gamble with the amount of money you're okay to lose. Now, that amount of bitcoin you had before is more than the loss that you did. But you need to cheer yourself up, it's not the end and there's always a chance to become better at holding your bitcoins.
