What should be done about the real-time strategy of real-time retailers?

I have hired several strategies and lost money on my rent. Only 17 years of official termination of the platform is real money, unfortunately the golden age has passed and I have not accumulated the original funds. I've been groping for a long time and haven't found the right one, or even lost any money. Recently, I just ran out of money, I was able to work for a while, now I can't, contracts and cash are too tight.

I've always been interested in the strategies of inventors on the real world, and I think there must be a game plan, which I think is also true. I feel that it is too expensive to spend money on research by one person, hoping that my classmates can share their experience together and pay less for tuition.

We're going to talk about coin circles, new coins, real-world strategies, analyze the feasibility, show the real world, the most convincing thing. The other is that all the providers of the current strategy do not disclose how many users they have, and they make a loss in proportion.

I've been speculating on others with good intentions, although some real-world strategies have a good yield curve, but one day it's at my expense or even exploded. Maybe it's my own not adjusting parameters, maybe it's extreme behavior, or even some strategies require users to have some kind of speculative talent. But I can't dare to try again, the cost is too high. Some strategy providers can still explain, some simply don't care, even black out.
