 - The metadata methods (`symbol`, `name`, `decimals`, `total_supply`) for ERC20 are optional, so around 10% of the
 contracts are missing this data. Also some contracts (EOS) implement these methods but with wrong return type,

+- Specify either `--start-block` or `--last-synced-block-file` option. `--last-synced-block-file` should point to the 
+file where the block number, from which to start streaming the blockchain data, is saved.
+- Use the `--lag` option to specify how many blocks to lag behind the head of the blockchain. It's the simplest way to 
+handle chain reorganizations - they are less likely the further a block from the head.
+- Use the `--chain` option to specify the type of the chain, e.g. `bitcoin`, `litecoin`, `dash`, `zcash`, etc.
