=====================================
Bitcoin Block Halving prediction
=====================================
bc=954044
gbt=1231006505
bbt=1781669847
This is average time to mine a block
(1781669847-1231006505)/954044
bts=577.1880173367084361848759
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 19 04:55:00 UTC 2028
-------------------------------------
Next palindrome will be 954459
predicted to happen at this time:
Fri Jun 19 22:49:40 UTC 2026
-------------------------------------
Current mining epoch number is 473.
The next fortnight happens in block
955584 and probably around this time:
Sat Jun 27 11:11:56 UTC 2026
