=====================================
Bitcoin Block Halving prediction
=====================================
bc=947593
gbt=1231006505
bbt=1777739477
This is average time to mine a block
(1777739477-1231006505)/947593
bts=576.9696431171999822708881
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 13:13:27 UTC 2028
-------------------------------------
Next palindrome will be 947749
predicted to happen at this time:
Sun May 3 17:31:24 UTC 2026
-------------------------------------
Current mining epoch number is 470.
The next fortnight happens in block
949536 and probably around this time:
Fri May 15 15:55:29 UTC 2026
