=====================================
Bitcoin Block Halving prediction
=====================================
bc=930517
gbt=1231006505
bbt=1767324923
This is average time to mine a block
(1767324923-1231006505)/930517
bts=576.3654416142406702503336
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 9 04:59:55 UTC 2028
-------------------------------------
Next palindrome will be 931139
predicted to happen at this time:
Tue Jan 6 07:10:22 UTC 2026
-------------------------------------
Current mining epoch number is 461.
The next fortnight happens in block
931392 and probably around this time:
Wed Jan 7 23:40:42 UTC 2026
