The page is cubdefi.com/

It will take you a day to understand all this. It will feel complicated in the beginning, and quite easy at the end.

Basically on this page you can exhange coins, and you can put coins into a 'den' and get daily percentage, or you can get pairs and put them in a 'farm' and get higher percentage.
Payout is the CUB token. I do trust it (it is made bei leofinance), but as always, investing is a risk. Maybe it suddenly disappears one day?

You will need to install Metamask, a wallet extension you need to hold your coins in to be able to interact with cubdefi. And you might have to add Binance Smart Chain as a network in Metamask.
You also need a bit of the BNB coin to pay for transactions in the Binance Smart Chain network (give me a shout if you are at that point).
And you need to connect Metamask with your leofinance (if you have leofinance page open and go to Metamask, you should see a connect button).

If you have that all, you can start like this:
You will need to have LEO. This you change ('wrap') into bLeo at https://wleo.io/bsc, the exact explanation you can find here: https://docs.cubdefi.com/tutorials/how-to-wrap-leo-into-bleo

With this bLeo you can now do different things. For example, you can go to 'Trade' - 'Exchange', on cubdefi.com, exchange you bLeo for CUB. The next step that is simple is to put the CUB in a Den. For this go to 'Dens', 'Unlock Wallet' and 'Approve Contract' (accept with Metamask). Then you click on '+' and choose the amount you want to stake. Done. You can unstake it anytime, and will see it in your Metemask wallet again.

From the moment you stake it, you will start earning. 'Harvest' means your earnings go to your Metamask wallet, 'Compund' means you add your profits to the Den.

So much for now, browse through the 'Docs' on cubdefi.com, read articles on leofinance and soon you will know your way around.
