I was a bit worried from last few days regarding the high gas fees because I've to pay 10 to 15$ per transaction, that's a huge amount for me as fees, so I started to search regarding the gas fees, and found that defi is the only reason that makes the gas fees that high ,due to the huge trend of defi it makes the ethereum network so much busier that we've to pay more than usual for gas fees ,what you think about it ,help me understand current situation for being so high fees.
