Well, BTC definitely looks like it could reach those heights. Its just a matter of time, I think and soon it can become a great alternative. There are already so many people interested in investing in BTC. It is also a great long term investment. Many beginners choose to begin their journeys by investing in bitcoin. So, yeah, there is hope.
Investment asset and money are not the same. Some shares can be good for investing but you'll hardly use them for paying for your coffee in a cafe. So when we talk about Bitcoin, it has different sides: you can use it for trading or investing but you can also use it as money, but as for its currency nature, it still has some known technical problems. For instance in El Salvador they use Lightning Network for solving some of those problems, but it is still layer two decision. I'm sure we'll see some new blockchain inventions which will solve all technical problems at the level one and Bitcoin will become a world popular currency besides being a good investment already. But as for now it is not yet.
