=====================================
Bitcoin Block Halving prediction
=====================================
bc=947893
gbt=1231006505
bbt=1777910637
This is average time to mine a block
(1777910637-1231006505)/947893
bts=576.9676060825366549424302
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 12:37:48 UTC 2028
-------------------------------------
Next palindrome will be 948849
predicted to happen at this time:
Mon May 11 01:16:58 UTC 2026
-------------------------------------
Current mining epoch number is 470.
The next fortnight happens in block
949536 and probably around this time:
Fri May 15 15:23:14 UTC 2026
