Good, for people who do like Bitcoin and he has a lot of money and is not good for people who have no money to buy bitcoins 
. Bitcoin is an asset or can also be a saving and I am very happy to play, invest, trade Bitcoin and Altcoins 
It is really bad for someone to invest in something and they can't afford it. That would really bring them down but for me, the bad thing about bitcoin is that it is a decentralized crypto currency. Despite the big pumps and big profits, they are getting. Even if it faster to transact than other currencies, it will still be decentralized and that means it would never be a currency.
