=====================================
Bitcoin Block Halving prediction
=====================================
bc=952146
gbt=1231006505
bbt=1780431667
This is average time to mine a block
(1780431667-1231006505)/952146
bts=577.0381695263441464395728
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Fri Mar 17 09:12:40 UTC 2028
-------------------------------------
Next palindrome will be 952259
predicted to happen at this time:
Wed Jun 3 14:27:52 UTC 2026
-------------------------------------
Current mining epoch number is 472.
The next fortnight happens in block
953568 and probably around this time:
Fri Jun 12 08:16:55 UTC 2026
