=====================================
Bitcoin Block Halving prediction
=====================================
bc=962020
gbt=1231006505
bbt=1786462070
This is average time to mine a block
(1786462070-1231006505)/962020
bts=577.3840331967805276599991
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 21 14:05:17 UTC 2028
-------------------------------------
Next palindrome will be 962269
predicted to happen at this time:
Thu Aug 13 07:23:58 UTC 2026
-------------------------------------
Current mining epoch number is 477.
The next fortnight happens in block
963648 and probably around this time:
Sat Aug 22 12:34:11 UTC 2026
