Patrick Tobler, CEO of NMKR, believes there needs to be an increase in the number of transactions on Cardano to keep the chain sustainable. In a recent post on X, Tobler noted it would be detrimental for Cardano if running stake pools became unprofitable. In his opinion, replacing staking rewards coming from the treasury through transaction fees would be a step forward toward achieving the sustainability of Cardano. He encouraged the Cardano community to engage in processes that would increase the number of transactions on the blockchain’s network.
