=====================================
Bitcoin Block Halving prediction
=====================================
bc=954993
gbt=1231006505
bbt=1782212852
This is average time to mine a block
(1782212852-1231006505)/954993
bts=577.1830472233333403141799
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 19 03:28:01 UTC 2028
-------------------------------------
Next palindrome will be 955559
predicted to happen at this time:
Sat Jun 27 05:52:17 UTC 2026
-------------------------------------
Current mining epoch number is 473.
The next fortnight happens in block
955584 and probably around this time:
Sat Jun 27 09:52:47 UTC 2026
