To make matters worse, yields from lending and trading activities change rapidly. Sophisticated DeFi yield earners are familiar with constantly having to rebalance their portfolio of assets across many competing platforms. This is time-consuming and expensive as gas fees once again eat into yields. In addition, it is time-consuming to calculate real ROI as APYs are unstable and constantly fluctuating. There isn't a manageable unit of account. As a result, while DeFi is growing rapidly, it still makes it difficult for many cryptocurrency users to participate.
