honestly, its like crypto mining, while mining itself can be profitable, and many times not, there is almost always a profit in running a "mining pool", there are bigger investments and a little work, but dine properly, it works

so... likewise, the best position in trading is owning and/or running a service structure that  profits, the investment is much bigger and there are legal challenges, but almost every crypto "service" can be so up and down, that the gedt get is provide tge service, i think that, other than freak investment returns, the highest profit out there is coin creation, byt ut requires a good amount of knowledge and a semi decent pc setup, that existing, people pay in the thousands for something like five hours of computer work, of which the coder puts in about an hour, i could be wrong about the numbers though
