Yes. Bitcoin is giving us more profits every year because obviously its price is gaining more growth as years goes by.
Not sure where you are getting this idea because the market caps rises and drops everyday and so does the price. You are wrong that every year price rises - the prices fall as well. Year 2018 was a good insight into how manipulated the prices can become.
Just invest in a long term and definitely you'll make big profits if you also invest with more patience and dedication in the crypto market.
That is correct though. Long term value of bitcoin is rising. But the last 2years have been up and down and even today bitcoin is below the 10k mark which is low according to many bullish traders.
