I send my USDT from poloniex to bittrex, but I fill BTC wallet  :-[
Can I recover it??

No hope in recovering your tether from an exchange. You have to get the private key from where you sent the tether then import that to a wallet that supports tether. Chances of bittrex giving you their private keys is close to none. Always double check or even triple check your address next time to avoid this kind of mistake.

Wouldn't the actual address format be different though?

And this is a perfect example as to why the crypto technology is still in its early days. Why on earth is there no check on if coins are being sent to a non-0X addresses if you are sending Tether? The exchanges could make this address check, but it would be great if it was incorporated into the cryptocurrency currency instead in case exchanges are lazy and do not develop such a user-friendly feature.

It could be done but exchanges do not seem to care about their customers funds.

Indeed - I know binance wont let you send things to the wrong format of address - but in certain cases this wont stop it = tether to EXP address etc. Its been an issue for some time.
Very rough to straight up burn money IMO - but Ive done plenty

Here is Bittrex cross-chain recovery policy.

If your deposit was worth less than $5000, than consider it a lesson learned.

I honestly don't blame them for having that 5K threshold.  Otherwise they would have to employ a bunch of people to fix the mistakes of all the noobs/drunk traders/idiots/uninformed people who send shit where it wasn't intended to go.  Triple check everything, every time.  If you're not sure, check again.

On the other hand, it would be nice if it just didn't allow you to send A-Coin to B-Coin address.

This. A good wallet will prevent coins being sent to an incorrect address format. For two entirely different techs (like USDT - BTC) this should be easily preventable.

Well, USDT use the same address format as Bitcoin.
So every valid Bitcoin addresses are also valid USDT addresses.
There is no way to differentiate them.

Somewhere I read that both wallets belong to the same person, whether they use both or not.  As in, someone who has control of BTC wallet address 123 doesn't have to worry about another person getting USDT wallet address 123 given to them.  Is that correct?

Yes,but only if you have control over the the private key corresponding to address 123.
This also holds true for bitcoin gold and bitcoin cash.

Most online exchanges give you a "wallet" but don't give you access to the private key.

I don't think you actually understand that that is impossible.

A bitcoin adress is exactly the same as a USDT adress. They are both generated with the same keys.

So a USDT adress will also be a valid BTC adress. Any wallet prohibiting sending anything to a USDT adress will also prohibit to sending to every bitcoin adress.

No I'm sorry. No cross chain transactions.

No you cant..
