=====================================
Bitcoin Block Halving prediction
=====================================
bc=969991
gbt=1231006505
bbt=1791193251
This is average time to mine a block
(1791193251-1231006505)/969991
bts=577.5168723041014771255845
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 23 04:49:58 UTC 2028
-------------------------------------
Next palindrome will be 970079
predicted to happen at this time:
Mon Oct 5 23:47:52 UTC 2026
-------------------------------------
Current mining epoch number is 481.
The next fortnight happens in block
971712 and probably around this time:
Fri Oct 16 21:45:57 UTC 2026
