Investing is considering us preparing our future and I really appreciate those students who think about investing earlier despite of their situation. Indeed, it was a struggle for us to start especially if we only had a small income but if we really care about our future, we should have to do it. Perhaps, it was only hard at the start but in the later part when we already adjusted our spending habits, that seemed too easy. We don't need to make an excuse because we don't have money but instead, we think about how to grow our income so we have an excess money for this.
One thing about Bitcoin is that you don't need a huge capital to start investment rather you can start investing with 10$ weekly or monthly, whichever option suits you. There are many examples available where people keep investing small amount of fiat in Bitcoin and with time that small amount has grown to give good ROI.
Despite the fact that Bitcoin price has gone up to 48k$, investing in bitcoin is still profitable provided you have patience to keep investing for long term.
