Use the "SEND" button if you want to send an Asset or Waves (WavesUSD, WavesEUR, WavesETH, WavesBTC, WavesZCash, WavesLitecoin or another assets) to another Waves lite client or to the exchange that accepts this Asset.
In this case, the address to which you send the Asset/Waves should start with "3P ..."
Use the "WITHDRAW" button if you want to withdraw a Fiat or Coin (USD, EUR, BTC, ETH, ZCash, Litecoin) to an external network, for example, to the BTC wallet, to the ETH wallet or transfer your Fiat to the bank.
For any of these actions, make sure that you have 0.001 Waves to complete the transaction.
