I often send money from Noones from my trading profit to that wallet and then I lend out money to make more profit, but instead of making more profit I ended up losing the profit becasue I trusted a scammer.

Or if I get some winnings in Stake I sometimes also send money there.
Again thanks for the information and this will be changed for future loans

You can still do this, even if you use different addresses every time. There's absolutely no need to use the same address for "a lot of stuff", as your wallet can generate an endless number of addresses at no cost whatsoever. And even if your funds are spread out across multiple wallet addresses, you can still consolidate and spend them in a single transaction by combining multiple inputs.
I thinked first I needed to have same adress for all my things on Bitcointalk since on the profile you can add your bitcoin adress for some saftey reasons.
I have other wallets to that I use. But next time I will one adress for each loan
