Examining the challenges bitcoin faces including scalability issues, price volatility, and environmental concerns relating to mining
In my personal case I can't see any disadvantage or downside of Bitcoin especially in this digital age such a digital currency is playing a very important role in the economic development and improvement of the current civilization.
Didn't we experience the scalability issue several times? When someone wants to play the network transaction fee, all these people have to do is congest the network. It could not have been an issue if there was no problem with the scalability of Bitcoin. I agree that developers are working on it but yet it has not been fully solved until now. With these congestions also comes the transaction fee hike.
Regarding with price volatility, it is also one of the attractive factors of the Bitcoin market. So I would not consider it as a disadvantage of Bitcoins.
Environmental problems regarding Bitcoin mining have been debunked many times I don't know why people still use these things to give a negative impression of Bitcoin.
