=====================================
Bitcoin Block Halving prediction
=====================================
bc=954543
gbt=1231006505
bbt=1781949489
This is average time to mine a block
(1781949489-1231006505)/954543
bts=577.1792437017046883119059
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 19 02:21:28 UTC 2028
-------------------------------------
Next palindrome will be 955559
predicted to happen at this time:
Sat Jun 27 04:51:43 UTC 2026
-------------------------------------
Current mining epoch number is 473.
The next fortnight happens in block
955584 and probably around this time:
Sat Jun 27 08:52:12 UTC 2026
