It should be, "Bitcoin investment at the right time is the key to success." because at what price and at what time in the cycle you buy makes a huge difference. People who bought Bitcoin at $69k cannot say the same because they've bought at the wrong time, maybe not completely wrong because they will eventually get in profit if they are patient enough, but because of the wrong timing, they had to wait for years for the market to complete another cycle and then get back. So, timing matters as well.
Anyway, you shouldn't feel bad at all after what you achieved with your investments. Your small investments grown enough to make you capable enough of buying yourself a laptop should be enough for you as it was your first investment and you already achieved something with it where most people barely get anything out of their very first time investing in something.
Timing affects outcomes, but in Bitcoin's chaotic world, the "perfect time" is unclear. The concept that there's a perfect investment time ignores market volatility. Bitcoin prices fluctuate, making the "correct time" retrospectively evident but potentially uncertain. Every investor starts with different goals and thresholds. Some value short-term swings, others long-term gain. Your ability to turn a tiny investment into a concrete asset shows this versatility. Instead of finding the "perfect time", you succeeded by sticking to your investment approach. Dont forget, Bitcoin's value goes beyond price. Decentralized empowerment is demonstrated by this technological and financial breakthrough. Limiting attention to timing and profit ignores this. For its values as well as its prospects, we invest in Bitcoin.
