Which exchange allows the investor to own the private keys?

[Cvriv]

Im new to cryptocurrency and want to try it out. I want to own my coins. I would actually like to use my own version of a paper wallet. I need the the private keys and addresses of my transactions though. Which exchange allows this?

Everywhere i go i read about securing keys and how its the safest way to secure your coin, but mentions nothing about where to invest such that you get the keys. All the exchanges keep the keys, which blows my mind.

If what you mean by "exchange" in this case is centralized exchange then as far as I know there is none. The address that's provided by the exchange usually already integrated into their system that runs automatically therefore an user owning private key could disrupt the system and make chaos, that's why in the case of retrieving cryptos that was sent wrongly to the address that's owned by the exchange usually takes a long time. but if the centralized exchange also offers wallet services or owning some wallet services they could provide the private key (the wallet service separated from their exchange service). My recommendation is just use your paper wallet and send the coin when you want to make trade or just use DEXes

DEX is the only choice but you must not be surprised if you must have dealt with a high transaction fee when it comes to the dex that builds in the non scalable chain like ethereum.
Your key and your money.
You can try to use uniswap (ethereum chain) or pancake swap (binance chain)
You just need to connect your wallet through metamask. it will much more secure rather than try to sign in use your privkey just like etherdelta did in the past.
