First trading is not a business. You can trade at your own will but dont make it your business or your first job. This is because those traders who are actually being investment bankers have a lot of failsafes to keep their money safe and they dont venture into crypto much - being logical for them is to put their money in stocks which are much safer.

While this is also true that the public figure traders who call themselves big traders are actually frauds. They only run on their private group subscription to pump and dump their own shitcoins. Take you own pick on whether you want to trust someone else with your money or yourself.
