You can choose to fund your Bitcoin account via an On-Chain bitcoin deposit or by paying an Off-Chain lightning invoice. If you are unsure of which to pick please read the below summary of the two deposit methods:
On-chain transactions are bitcoin transactions that are recorded on the blockchain and often have higher transaction fees. The larger the fee you pay, the greater the incentive the miner has to process your transaction over the list of other pending transactions. The advantage of on-chain transactions is security and finality.
The lightning network was created to enable instant micro-transactions at an extremely low cost. The average transaction time on the bitcoin blockchain can be around 10-60 minutes depending on the fees but the lightning network transactions are near-instant as they happen Off-Chain.
Lightning Network transactions are cheaper and faster than On-Chain transactions but have smaller transaction amount limits.
This makes the lightning network perfect for micropayments.
