=====================================
Bitcoin Block Halving prediction
=====================================
bc=954503
gbt=1231006505
bbt=1781932685
This is average time to mine a block
(1781932685-1231006505)/954503
bts=577.1858263558874556837896
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 19 04:16:39 UTC 2028
-------------------------------------
Next palindrome will be 955559
predicted to happen at this time:
Sat Jun 27 06:36:33 UTC 2026
-------------------------------------
Current mining epoch number is 473.
The next fortnight happens in block
955584 and probably around this time:
Sat Jun 27 10:37:02 UTC 2026
