But there's also a dark side to all this fun, remember that where there's money to make, there's also people that will take advantage and scam people out of their hard earned money. It would be better if there's some precautions before getting into that everyone has to read so they don't fall for scams even if they're newbies.
I don't think it's all about fun but most people feel it's really bitter experience in initial stages. Ignorance, scams, FOMO, speculation etc, makes big trap to many newbies. Many are experience unbearable losses. Different people have different experience so as a newbies we should be aware the basics, selection of coins etc. In my knowledge apart from all these "empiricism" is the key. So trade, invest and make profit but not be a greedy one. Control your emotions when making decisions and always remember "experience makes a person perfect"
