so if i get this correctly, in your platform there will be 2 kind of users, investors (those who follows signal) and trader expert (those who make prediction). the higher the prediction rate by expert, their followers and the rewards will also increase. this create an ecosystem where the expert can influence lots of users and possibly cause a self-fulfilling prophecy isn't it? i mean if someone influential said bitcoin can go down to $1k, then it's possible their followers will sell asap.
Thanks for your concern!
In absolute theory, the concern that a Trader could become so pre-eminent as to trigger a self-fulfilling prophecy is possible. This has happened in the real stock market with regards to currency speculators and in real estate speculators with property. However, just because something is possible does not make it at all probable. In order to have that kind of pull as a single investor, you would have to be unimaginably large and noticeable in the market. At current, nobody is anywhere near this in the cryptocurrency market. For example, if someone were to buy or sell millions of USD worth of bitcoin, it would barely shift the price by 1%.
