Why are there so many transactions? is it because bitcoin is getting more popular?


I sent 100 bucks and the fee was $2.70, i thought it was too high so i changed it to 0.50cents, and now its been 2 days and my transaction is unconfirmed,

it seems it wont go thorough,  


im thinking its time to cash out half my bitcoins, and take home some profit in case it crashes
