=====================================
Bitcoin Block Halving prediction
=====================================
bc=938424
gbt=1231006505
bbt=1772105147
This is average time to mine a block
(1772105147-1231006505)/938424
bts=576.6029698697285345126142
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 12 02:16:39 UTC 2028
-------------------------------------
Next palindrome will be 938839
predicted to happen at this time:
Sun Mar 1 05:53:57 UTC 2026
-------------------------------------
Current mining epoch number is 465.
The next fortnight happens in block
939456 and probably around this time:
Thu Mar 5 08:43:21 UTC 2026
