This is not an update I was waiting for to be honest. Since very recent there will be a cap of 20,000 nominators on PolkaDot at any time. I believe it should be solved as soon as possible because:
1. I don't like the fact nominators are selected randomly:
2. Not everybody will be able to stake their DOT, which can interfere with inflation and accessibility of the platform.
3. If the limitation is not fixed in future - I don't understand how can Polkadot scale in production. At some point 20K limit will make staking available only for DOT whales with minimum 1K-10K DOT coins to stake, anyone else will be left behind.
Waiting for updates.
