Since its launch in 2009 by Satoshi Nakamoto, the presence of Bitcoin really creates pros and cons. There are a number of positive and negative views related to the cryptocurrency because of the fact that the 'currency' was just launched after the financial crisis 2007-2008. In contrast to the current conditions, the beginning of this currency is difficult to be accepted even though the market has paid a massive media to introduce and polish this beautiful Bitcoin side.
but since bitcoin is already in use many people they all choose bitcoin as their future money
In a sense you are right. But the thing is that I do not agree with the statement about "the presence of bitcoins really creates pros and cons." Clearly, bitcoins is not the one creating the pros and cons or should I say its presence as what you have stated. The way I see it, the day that it was first thought of by the person satoshi nakamoto(or team satoshi), it already has pros and cons. And as technologies progress and through its continued use by the people, we learn about all the cons and pros and become the ones who create some of them. That is what I think.
