=====================================
Bitcoin Block Halving prediction
=====================================
bc=923584
gbt=1231006505
bbt=1763123621
This is average time to mine a block
(1763123621-1231006505)/923584
bts=576.1430902407466556949279
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Mon Mar 6 12:08:45 UTC 2028
-------------------------------------
Next palindrome will be 924429
predicted to happen at this time:
Thu Nov 20 03:47:41 UTC 2025
-------------------------------------
Current mining epoch number is 458.
The next fortnight happens in block
925344 and probably around this time:
Wed Nov 26 06:13:52 UTC 2025
