Is it the most reasonable choice to sell BTC now and turn your attention to other investments?
You don't need to be good at management to have patience. I'm sure you're aware Bitcoin has a brighter future so as a result you should hold on more ... Also the market now might just be building up for a bull run coming up soon so have patience and hold on to your fraction of bitcoins. Joining investment is good if you have any genuine one but don't rob Peter to pay Paul keep your Bitcoin join good investment from the little you have to spare so you don't lose all and when you're gaining too you gain all!
