In every market, there is no such thing as "rise to infinity". All markets are moving sideways although in Bitcoin, the trend that we are seeing in the past 12 years is a move upwards then a big correction then big upwards movement. It is making a higher lows every time . Thinking that Bitcoin will rise to infinity is a stupid mindset.
Avoid buying when the price continues to rise, crash will happen sooner or late.
Reduce your risk by diversifying your investment: It may not be investment advice but put a significant limit on your risk.
Nothing rises to infinity.
Avoid panic and emotions trading
2. Diversification is indeed a good strategy to lessen your risk but it isn't applicable to those investors who doesn't have that much of money. If you only have small money to invest like $100 or $200, investing in one or two safest coins would be the best choice like BTC or ETH or those coins at the top. Those investors that have larger money can diversify as much as they want .
3. The phrase "rise to infinity" isn't applicable to market as it moves in cycles. What only is infinity in every market is cycles .
4. Being emotionless is one of the hardest things to do especially in investing or even in trading. I have experienced it already and being emotional in every investment doesn't benefit you that is why I learned being emotionless for quite some time. Now I don't care if my portfolio goes down or up anymore. At the same time, I don't panic anymore because I removed my emotions already whenever I invest .
