You are not alone, I also have the dream of getting some Bitcoin before 2025, but I believe the chances of making a fortune with Bitcoin is now very slim compared to years back, I know many people don't want to hear this but it's a fact, i do not expect Bitcoin to bring me x15 or x20 like other risky projects, it's not possible anymore, until a wider ray of hope shined down on Bitcoin adoption, maybe in some several years to this time. I am only using Bitcoin to leverage my crypto portfolio, to stay on a more safer side, Bitcoin investment is more safer than every other coins in crypto space but many other coins will get people rich than Bitcoin, this is why we have to expose ourselves to some risks, I don't see why anyone will say no to this, many are into gambling anyway and they take risks here and there, I'd say it's worth the risk.
Though it's not about making a fortune if your dream is only to accumulate a certain amount of Bitcoins, it's still true that it is not as easy as it used to be before because the price of Bitcoin used to be very low back in the day and someone could easily buy one Bitcoin if they had a good income. However, nothing is impossible, one can still achieve one goal if one works hard for it, and we already know that the market can crash anytime to provide an opportunity.
Most people these days are struggling to accumulate enough Bitcoins that they can hold for the future through trading but that requires a lot of hard work and a lot of dedication, however, I don't recommend taking a lot of risks through trading new cryptocurrencies as that can cause you losses sometimes.
