=====================================
Bitcoin Block Halving prediction
=====================================
bc=944511
gbt=1231006505
bbt=1775854039
This is average time to mine a block
(1775854039-1231006505)/944511
bts=576.8561267617563355468220
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 15 04:06:54 UTC 2028
-------------------------------------
Next palindrome will be 945549
predicted to happen at this time:
Fri Apr 17 19:06:55 UTC 2026
-------------------------------------
Current mining epoch number is 468.
The next fortnight happens in block
945504 and probably around this time:
Fri Apr 17 11:54:17 UTC 2026
