Yeah I agree, but if you think about it it should be more predictable than stock markets. Because you can:
 

• see how many tokens are on the exchange
• see big holders and their movements
• monitor exchanges and their deposits/withdrawal transactions

All this information should help you make better decisions, I believe we should make more predictable then stock markets. I think (wild theory) most people are focusing on wrong information to focus,
all those signal groups / 17 y.o youtube traders / rumors.

I have created simple notification bot/app/platform for few tokens/markets deposits and test traded for lower risk trades, of course I can't make big enough sample of trades to say its working, but so far I'm satisfied with the outcome. That said I believe this bot/app/platform would be more powerful in hands of traders. // Disclaimer this is not solution which is  money factory, passive income or any other get rich quick scheme. I'm just relaying information straight to the user.
If you are interested you can check twitter, write me a Pm,  I'm now focusing on low market tokens as to POC.
