I made a post about iceberg order, take a look to get an idea of what it's about, it's pretty easy to understand.

Is the price of cryptocurrencies different at each exchange? Or is it the same... for example, is the price of BTC the same on Coinbase and Binance? And what do you think about these Iceberg orders that split your buy/sell order into small amounts? In your opinion, do they hinder or help the market?
