Just as a sensible income is needed to start investing, 2 more things are needed
1 Basic knowledge about Bitcoin
2 Faith in Bitcoin
If you do not have basic knowledge about Bitcoin, then you will never know what Bitcoin is and how we can profit from Bitcoin. If you do not have faith in Bitcoin, then you can sell your holdings during the decline. So you have to have faith in Bitcoin. If a new person is scared, it is very natural, but he has to be careful that he does not get so scared that he has to sell his holdings. Along with investing, by gaining knowledge and gaining experience, you will be able to learn to deal with the decline gradually.
When it comes to Bitcoin knowledge and trust are very important for any investor because it is not about predicting the best time to buy, but to understand what you're investing in and why you believe in it. If you understand how Bitcoin works, how it benefits investors, and why people value it, you will feel more comfortable holding it even if the price falls, but if you don't understand Bitcoin, you will fear when the prices change and sell at the wrong time.
The trust in Bitcoin comes from understanding its future value, which is better than a short term investment, the price always changes, and that is normal, but the goal is to invest for the future. And if you continue to learn, you will be able to deal with the dips, stay patient, and do not invest more than you can afford to hold.
