Deposit refers to the option of crediting funds using external funding options such as Crypto Exchanges or another form of crypto vendors. In essence, Bombastic provides a receiving address and your cryptocurrency is under some other address somewhere else. What you do is send funds from one address to another - usually a Crypto Exchange to Bombastic.

Bombastic provides you with a RECEIVING ADDRESS (Wallet address) for your cryptocurrency. This is a UNIQUE address assigned to your account only. In order to deposit to Bombastic, you must have crypto currency available somewhere else. That "else" place is usually Crypto Exchange where you need to use the said Crypto Exchange's SEND facility.
