Successful investing in crypto requires us to equip ourselves with information about a coin or token's market cap, volume, and whether it will be inflationary or deflationary.
Both a CEX or a DEX can help us trade crypto and cash; however, some transactions will cause us to pay taxes.
Trading and transacting crypto isn't free. Crypto exchanges make money whenever we make trades, regardless of whether it's cash-to-crypto or crypto-to-crypto. We also pay transaction fees as an incentive for miners and validators to verify our transaction on the blockchain.
There are numerous other cryptocurrencies out there that allow us to complete transactions and some enable us to participate even more in decentralized finance.
