That is not right.It is wrong.Bitcoin can still be helpful Many people are already benefited by working or investing. Because it is the best opportunity to earn money.Bitcoin is giving you profit and makes your life better, then bitcoin is more than being so useful at all.So,to say that it is useless seems to me really wrong.It is useful and helpful Cryptocurrency.
You were wrong with your point of view when thinking that Bitcoin is useful. Bitcoin is not a practical application, and it is just a portfolio to make a profit for investors. Bitcoins are manipulated by whales to make their fairness risky.
