=====================================
Bitcoin Block Halving prediction
=====================================
bc=954135
gbt=1231006505
bbt=1781725623
This is average time to mine a block
(1781725623-1231006505)/954135
bts=577.1914255410130212045243
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 19 05:54:39 UTC 2028
-------------------------------------
Next palindrome will be 954459
predicted to happen at this time:
Fri Jun 19 23:43:53 UTC 2026
-------------------------------------
Current mining epoch number is 473.
The next fortnight happens in block
955584 and probably around this time:
Sat Jun 27 12:06:13 UTC 2026
