OH MY GAS!!!
I have experienced sending tokens to an exchange and the transaction is successful but why are my tokens still in my wallet? Is it because I changed the gas price from 41 to 38? If that is the case, how do I know the recommended gas when sending tokens so I will not commit the same mistake again?
You should wait little bit and check later, if the transaction is successful your tokens are will be on exchange and balance in your wallet will be zero.
How much gas is needed you can check on ethgasstation. Here is the link.
