Trading is now best way because the price of bitcoin is increasing day by day
That is ok if you always trade the good coin or coin which is increasing its value daily. But in bitcoin you can not earn profit now because value of bitcoin is continuous increasing and you do not like to buy at the current price due to high value of bitcoin now.
You need to be tolerant and already forget about the excess profits on trade when you earn on the difference in the price of Bitcoin. It used to be strong leaps and differences in the pricing of the crypto currency, so there was an opportunity to buy cheap and sell expensive. Today this is not observed, So you need to be patient.
