Delegated steem to new minnows fell from 30sp to 15sp... Why?

Did anyone else notice that the amount of delegated SP for new accounts has fallen?

When I created my account on 1/3/2018 the account Hive account@steem delegated me with 30 SP or 57,000.000000 vests.

Later on 1/8/2018 the account Hive account@steem changed my delegated vests to 29,700.549089 VESTS

By dropping my delegated vests the rewards for my votes have been cut in half.

Why has the vest pool for new accounts halved so their votes are worth .01 only if they are above 81% voting power?

Is this going to be a game of diminishing reward power as more accounts are created?

I edited my orginal post to add something I found after. Refer to comments for exact time.

This afternoon the Hive account@steem account which delegates our SP has 326,484 SP that is undelegated. If we continue to add users at the same pace we have been earlier this year the steem account has 21,766 new users it can delegate (~15 SP) to before it is bankrupt. Given that we have added over 50k accounts in the 2 weeks of January, that means the bank wont have enough to cover new accounts being made next week.

When Hive account@steem runs out of SP to delegate will it cut the delegation in half again or will the steemit experiment fail?
