I hope, I'm not late for Bitcoin because Bitcoin already grew a lot.
No, you are not. Despite the fact that Bitcoin price has grown far beyond its starting price, there are still many more high prices it will cover. In 2021, the Bitcoin price saw an all-time high, but after that, the bear market set in and the market crashed again, which some people did not even expect after reaching a very all-time high. So, if you are consistent in accumulating your Bitcoin, just as you have only started, then you will make a profit in the long run. Don't procrastinate your investment, and don't invest harder than you can handle; otherwise, you might not be able to hold it for a long time. Also, remember that Bitcoin investment is not just a short-term investment.
