=====================================
Bitcoin Block Halving prediction
=====================================
bc=947719
gbt=1231006505
bbt=1777812351
This is average time to mine a block
(1777812351-1231006505)/947719
bts=576.9698286413708690330477
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 13:16:42 UTC 2028
-------------------------------------
Next palindrome will be 947749
predicted to happen at this time:
Sun May 3 17:34:20 UTC 2026
-------------------------------------
Current mining epoch number is 470.
The next fortnight happens in block
949536 and probably around this time:
Fri May 15 15:58:25 UTC 2026
