=====================================
Bitcoin Block Halving prediction
=====================================
bc=967391
gbt=1231006505
bbt=1789637743
This is average time to mine a block
(1789637743-1231006505)/967391
bts=577.4610891965201283450762
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 12:33:46 UTC 2028
-------------------------------------
Next palindrome will be 967769
predicted to happen at this time:
Sat Sep 19 22:13:43 UTC 2026
-------------------------------------
Current mining epoch number is 479.
The next fortnight happens in block
967680 and probably around this time:
Sat Sep 19 07:57:09 UTC 2026
