I think there is no need to wait for investing in Bitcoin. Because I myself bought Bitcoin when it was 25,000 and sold it at 40, thinking that this might be the highest price. If I lower it a little, I will buy it again. I kept waiting, but even after lowering it a little, the price kept increasing. I thought and waited a little longer, and after thinking, it reached 100, then I decided that there was no point in thinking anymore, I will buy Bitcoin with a part of my salary every month, so I started buying. Now I realize that I was wrong to wait. I think Bitcoin is an asset that may go beyond our reach in the future. So now is the right time to invest.
Congratulations, you've profited from your BTC investment, buying at $25,000 and selling at $40,000. Unfortunately, you didn't make a larger profit. If you had sold now, you might have made more money, but it would certainly be better to sell in 5 or 10 years. However, what has happened is certainly a valuable experience for you, and if you've thought about it and realized that holding BTC for the long term is necessary, you're probably in good shape now and are starting to consider buying BTC using part of your salary and saving it for the long term.
However, you must maintain an emergency fund because life in this world is full of temptations and obstacles. If you have an emergency fund, you will certainly succeed with your BTC investment. Experience is a valuable teacher, and buying BTC is certainly the right choice right now, as long as you buy with ready cash.
