=====================================
Bitcoin Block Halving prediction
=====================================
bc=953682
gbt=1231006505
bbt=1781465574
This is average time to mine a block
(1781465574-1231006505)/953682
bts=577.1929131587749807850197
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 19 06:20:41 UTC 2028
-------------------------------------
Next palindrome will be 954459
predicted to happen at this time:
Sat Jun 20 00:07:32 UTC 2026
-------------------------------------
Current mining epoch number is 473.
The next fortnight happens in block
955584 and probably around this time:
Sat Jun 27 12:29:54 UTC 2026
