yes, there are many difference between them, we cannot see or hold bitcoins, if we cannot withdraw it, we are earning also bitcoins but tool an hr or more with a big fee in every transactions that we made when we are withdrawing. there are many differences but one thing I can assure, is that both we can use it to pay our bills and to buy our foods. it both help us in pur needs.
