The most important rule for people to follow in my opinion is never invest any money that you cannot afford to loose. I know it is the #1 rule in investing in cryptocurrencies but it seems as though it is often overlooked.
Most of the people who have the FOMO or are looking for 'the next bitcoin' are new traders who don't fully understand what the cryptocurrency market is. Of course there is profit potential, but theres also the potential to loose every single penny they invest. Investors in the crypto market who want to 'get rich quick' by investing in the next big thing often loose most a good potion of their investment. Traders who are consistently profitable and have been for some time typically take safer and well rounded positions compared to new traders looking to use crypto investing as their way to 'get rich'.
