Bitcoin can rightly be called a future today. However, he lacks the confidence of the population. To fix this, you need to develop the technology blockchain, which in principle is now being done
Bitcoin is a future for a long time now. Bitcoin is invented more than 10 years from now so I don't think it can be only called the "future" these days because it is in the market and being used by a lot of people for years now.
Lacks "confidence" of the population? How can you say that? It started in cents and now it is on thousand, how can Bitcoin lack there? Price dumps are normal for Bitcoin since it is a decentralized cryptocurrency. Always remember that because of that decentralization, a lot of people or investors put their money on Bitcoin. Because of that decentralization and volatility, the price rose to what it is right now.
