Decide how you will trade

Often you can get better pricing using limit orders. But other times simple SWAP orders can get you the best price.

Understand path payments
DPath payments - unique to stellar since the beginning allow you to search all trading pairs for the best price. They are more powerful than SWAPs on Ethereum. For example perhaps going USDC -> XLM -> BTC would get your a better price than if you went directly from Bitcoin to Ethereum.  Path payments or "Swaps" also allow you to tap into Liquidity Pools which Limit orders to not.

Beware scam tokens!
As Stellar is inexpensive to launch tokens - there are many that are fraudulent. If on stellar.expert there is a triangle next to the symbol. It is probably fraudulent..

Put your XLM on Stellar and earn!
A more advanced concept is to stake your XLM and Bitcoin, Eth, XRP or other crypto in a Liquidity Pool and earn upwards of 3% yield. This also makes the stellar network better. We recommend staking XLM with crypto and stable coins with stable coins. So called "correlated assets" provide a better risk based return. For example you could stake USDC - BRL, USDC - KES, USDC - IDRT. Or on the crypto side XLM - BTC (ultrastellar), XLM - BTC LN from kbtrading.
