I don't think Cardano has much time left.
Staking rewards come from the reserve, and the reserve is down to just 13.6% of max supply. Rewards are only going to keep shrinking. The fees that are supposed to replace them covered just 0.67% of staking rewards over the past year.
Lower rewards mean lower returns for stake pools. It's already bad enough that Intersect proposed cutting minPoolCost specifically to "give small pools breathing room as block rewards decline."
Pools that can't turn a profit will eventually shut down, and once stake concentrates in a handful of big pools, the network gets less decentralized and less stable.
So what Cardano needs to focus on right now is simple: grow network volume, bring in users and liquidity, and get real products shipping that actually generate transactions.
We need to focus on strategies that refill the reserve and push the ADA price up.
