can i transfer direct ltc or ant coine bittrex wallet to binance wallet or i have to use outside wallet
do you mean any coin? if so, then yes of course, every exchange has a wallet address for certain coin and you have a unique address provided by the site so you can transfer easily. However, the fee would be different, usually, exchange set a fix fee that is higher compared to the fees when using a wallet.
Just try to look on videos, like youtube videos, I'm sure there's a lot of tutorial out there.
