=====================================
Bitcoin Block Halving prediction
=====================================
bc=961518
gbt=1231006505
bbt=1786156550
This is average time to mine a block
(1786156550-1231006505)/961518
bts=577.3677327229103117047089
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 21 09:20:01 UTC 2028
-------------------------------------
Next palindrome will be 962269
predicted to happen at this time:
Thu Aug 13 03:02:33 UTC 2026
-------------------------------------
Current mining epoch number is 476.
The next fortnight happens in block
961632 and probably around this time:
Sat Aug 8 20:52:49 UTC 2026
