=====================================
Bitcoin Block Halving prediction
=====================================
bc=943382
gbt=1231006505
bbt=1775146779
This is average time to mine a block
(1775146779-1231006505)/943382
bts=576.7967771308153740315439
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 14 10:48:17 UTC 2028
-------------------------------------
Next palindrome will be 944449
predicted to happen at this time:
Thu Apr 9 19:17:01 UTC 2026
-------------------------------------
Current mining epoch number is 467.
The next fortnight happens in block
943488 and probably around this time:
Fri Apr 3 09:18:39 UTC 2026
