=====================================
Bitcoin Block Halving prediction
=====================================
bc=947051
gbt=1231006505
bbt=1777397919
This is average time to mine a block
(1777397919-1231006505)/947051
bts=576.9391902450974180931986
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 04:20:31 UTC 2028
-------------------------------------
Next palindrome will be 947749
predicted to happen at this time:
Sun May 3 09:30:22 UTC 2026
-------------------------------------
Current mining epoch number is 469.
The next fortnight happens in block
947520 and probably around this time:
Fri May 1 20:48:23 UTC 2026
