=====================================
Bitcoin Block Halving prediction
=====================================
bc=936347
gbt=1231006505
bbt=1770969150
This is average time to mine a block
(1770969150-1231006505)/936347
bts=576.6687652454002144501830
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 12 21:28:05 UTC 2028
-------------------------------------
Next palindrome will be 936639
predicted to happen at this time:
Sun Feb 15 06:38:57 UTC 2026
-------------------------------------
Current mining epoch number is 464.
The next fortnight happens in block
937440 and probably around this time:
Fri Feb 20 14:57:28 UTC 2026
