To become a very good investors as a beginner you need to understand the following:

1. Understand what you’re investing in:
   As you would for any investment, understand exactly what you’re investing in. If you’re buying stocks, it’s important to read the prospectus and analyze the companies thoroughly. Plan to do the same with any cryptocurrencies, since there are literally thousands of them, they all function differently and new ones are being created every day. You need to understand the investment case for each trade. And must thoroughly understand the company very well.

2. Remember, the past is past
   A mistake that many new investors make is looking at the past and extrapolating that to the future. Yes, Bitcoin used to be worth pennies, but now is worth much more.
   Investors look to the future, not to what an asset has done in the past.

3. Watch that volatility
   Volatility is a game for high-powered Wall Street traders, each of whom is trying to outgun other deep-pocketed investors. A new investor can easily get crushed by the volatility.

That’s because volatility shakes out traders, especially beginners, who get scared. Meanwhile, other traders may step in and buy on the cheap. In short, volatility can help sophisticated traders “buy low and sell high” while inexperienced investors “buy high and sell low.”

1. Manage your risk
   If you’re trading any asset on a short-term basis, you need to manage your risk, and that can be especially true with volatile assets such as cryptocurrency. So as a newer trader, you’ll need to understand how best to manage risk and develop a process that helps you mitigate losses. And that process can vary from individual to individual:

1. Don’t invest more than you can afford to lose.
   Finally, it’s important to avoid putting money that you need into speculative assets. If you can’t afford to lose it – all of it – you can’t afford to put it into risky assets such as cryptocurrency.
   Whether it’s a down payment for a house or an important upcoming purchase, money that you need in the next few years should be kept in safe accounts so that it’s there when you need it. And if you’re looking for an absolutely sure return, your best option is to pay off debt. You’re guaranteed to earn (or save) whatever interest rate you’re paying on the debt. You can’t lose there.

That's all I can say for now.
