We've been told to buy when the price is low and sell when the price is high. This is pretty much the thumb rule in trading.

But that is not without conditions. It isn't absolute. It doesn't awalys guarantee profit.

Let us not forget the RISK. And risk correlates to volatility. High volatility means high risk. And since crypto market is a volatile market, risk is higher here.

So, the "buy=low, sell=high" strategy only works when you successfully manage the risk.

You can do that by:

1. Investing less than 5% of your total portfolio
2. Prioritizing other aspects of your finances ahead of investing in crypto
       - emergency fund
       - retirement savings
       - high-interest debt payment

In other words, invest only what you can afford to lose.

To sum it up--"Buy when the price is low and sell when the price is high, BUT invest only what you can afford to lose."

It may not guarantee profit but it can help cut down loss when the bear attacks.
