=====================================
Bitcoin Block Halving prediction
=====================================
bc=934590
gbt=1231006505
bbt=1769948030
This is average time to mine a block
(1769948030-1231006505)/934590
bts=576.6602984621080237237465
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 12 18:59:55 UTC 2028
-------------------------------------
Next palindrome will be 935539
predicted to happen at this time:
Sat Feb 7 20:14:40 UTC 2026
-------------------------------------
Current mining epoch number is 463.
The next fortnight happens in block
935424 and probably around this time:
Sat Feb 7 01:49:24 UTC 2026
