For me, Investing bitcoin is a big risky as no one is sure what will be the price of bitcoin in the future.
That is right. But so far the long time price trend for the bitcoin is up, so it could up as well as there is good adoption.
From about 6 months we are seeing that the price of bitcoin is increasing and it remained stable even in halving when a lot of people were saying that it will either crash so now due to the halving effect the price will continue to increase.
