# Do You Have These Questions When Doing DeFi Trading?

Since its birth, openness and accessibility have been the hallmark of DeFi to keep the conventional rigged mechanisms at arm's length. As a result, assets and products have been issued arbitrarily, resulting in the exponential growth of the data. CNBC reported that, in 2021, [the total crypto trade volume is $15.8 trillion, and DeFi transaction volume grew 912%](https://www.cnbc.com/2022/01/06/crypto-scammers-took-a-record-14-billion-in-2021-chainalysis.html?from=from_parent_mindnote).

When prepping for the trading, investors frequently need to answer questions like:

* Where are the alpha opportunities?
* What is the expected ROI?
* Which suspicious assets, vaults, and contracts do I have to avoid? 

During the trading, investors are interested in:

* When is the best time to begin?
* How to implement a successful strategy?
* How much is the appropriate cost to trade without spending too much?
* How to avoid being the victim of front-running?
* When to stop? 

All these questions need accurate information with precision extracted from the colossal volume of data.
