Ethereum used to be my favourite coin, until recently when the gas fee became unbelievable. I had to stop trading on Decentralized Exchange because of gas issues and learnt how to transfer my ethereum out of exchange using other coin like XLM and trx whose transaction fees are much lesser. I've learnt how to be more economical this period and trading on centralised exchange is much better. My favourite coin for now is tron and XLM.
