Risk Management:
Cryptocurrency world is well known for its rapid price fluctuations as I aforementioned. Determine how much of your portfolio you're willing to risk on a single project like if you have invested in multi projects or token It will be good for you to overcome your risk like we never know which project going to give you a fine and decent profit but keep in mind Diversify your portfolio after well-DYOR.
FOMO (Fear of Missing Out):
The FOMO (fear of missing out) can lead you to impulsive decisions which may lead to big mistakes. I have already covered this topic so I won’t write it again here but I would like to mention some points here which are always stick to your pre-determined plan while investing and if you have good sources it may help to overcome your FOMO. I am mentioning my FOMO topic here if you are interested you can read this one also.
Risk management and FOMO are two basic knowledge one needs to understand to stay profitable in the next bull run that is very much in anticipation. If you don't manage your portfolio enough to understand your risk level, most definitely you will be either Lossing or making leaser profits than you should have probably because you risked too much or you risked too little so it's very important you understand the concept of risk management even beyond diversifying your portfolio because if you have an investment in two coins and one is doing so well while the other is at some time doing so bad you see that your profits will be canceling out and you may end up breaking even or in losses and that's a very bad risk management.
You can aswell invest in just a single coin and still be very much profitable as you would have with other multiple coins , this aswell have some relativity with FOMO, you don't make impulsive decision because you think a coin is going to do so well or probably because you see that it has already attained a new ATH an you immediately hop on it, you may end up in losses and same applies with exiting early you will definitely leave good money on the table.
