=====================================
Bitcoin Block Halving prediction
=====================================
bc=932750
gbt=1231006505
bbt=1768708465
This is average time to mine a block
(1768708465-1231006505)/932750
bts=576.4689182858018913943807
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Fri Mar 10 11:10:45 UTC 2028
-------------------------------------
Next palindrome will be 933339
predicted to happen at this time:
Thu Jan 22 02:13:25 UTC 2026
-------------------------------------
Current mining epoch number is 462.
The next fortnight happens in block
933408 and probably around this time:
Thu Jan 22 13:16:21 UTC 2026
