Because they're only 42-coins that can be broken down in 0.00000001 dent. The smallest 42-coin value of 100,000,000 dents x 42 coins is the total amount of dents that doesnt required much computation compared to bitcoin and the network demands required a few nodes because only 42 coins need to be tracked and low exchange volume. .  the 42-coin ledger doesn't required much hard drive space and energy compared to bitcoin ledger so therefore lt puts the demands on your local wallet but its the key to it's survivability. Yes it seems unfair that the staking protocol favors the bigger the better wallet. What makes it worse they're only 42
coins total to stake on.. so the chance to stake on dents are impossible but the dents will be deflated and I predict at current trends of the value of a single 42-coin . In 2 years,  0.00000001 dents will be worth 1 USD dollar or higher!!! Even though you won't earn dents on staking your wallet, the staking value will grow and secures your investment at the same time..
