Making profit on this site is so easy bro. Here's a technique I use: Whenever you examine a market, try not to think about the current market price and convince yourself to "unsee" it since it can interfere with your judgement. Next, do some basic online research about the subject, try to use evidence and data to inform your prediction. Once you arrive at a percentage, denoted by Prob_me, you can compare this value with the market prediction, Prob_mkt, using this logit difference formula: log_diff = log(Prob_me/(1 - Prob_me)) - log(Prob_mkt/(1 - Prob_mkt)). The value of logit_diff indicates how much opportunities you're expected to have on this market if your prediction is accurate, and should inform how you diversify your investment. For example, I multiply this value by a constant factor depending on my net-worth to calculate the exact amount of mana I will invest in this market. This model is very very conservative since I enjoy having a smooth profit curve. To grow your profit faster, you can do something like e ^ logit_diff (corresponding to a linear diversification), (e/c) ^ logit_diff, or c ^ logit_diff. The moral behind these schemes is to invest more on markets you can take advantage of while keeping the risks under control.
