=====================================
Bitcoin Block Halving prediction
=====================================
bc=944313
gbt=1231006505
bbt=1775722382
This is average time to mine a block
(1775722382-1231006505)/944313
bts=576.8376588719430189534413
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 14 22:43:43 UTC 2028
-------------------------------------
Next palindrome will be 944449
predicted to happen at this time:
Fri Apr 10 06:00:31 UTC 2026
-------------------------------------
Current mining epoch number is 468.
The next fortnight happens in block
945504 and probably around this time:
Fri Apr 17 07:03:15 UTC 2026
