There is analytics which shows the health of  Easy Invest: https://beta.observablehq.com/@phantomydn/analysis-of-eth-pyramid

But you can calculate it manually. By now Balance of the contract is 1213 eth, invested amount is 1326. Each day pyramid pays out 1326*0.04 = 53 eth. So if new investments stop now the project will last at least 22.88 days. And you will receive back 22.88*4 = 91% of your investment.

That is, your risk now is only 8.5% ) And I really doubt that investments stop today or tomorrow or this week.

Easy Invest is now the healthiest project in crypto.
