If it makes you sad, you're way too emotionally invested in bitcoin. Just put it away in a wallet or cold storage and forget about it for a while if you can. This is bitcoin, where crazy price swings are more the norm than the exception--remember 2013?? So just hold it. If you keep trading you're almost guaranteed to lose money. And for the love of fuck, please listen to MRKLYE and don't gamble your bitcoin. He knows what he's talking about, just look at his trust feedback for a little glimpse into gambling madness.
