=====================================
Bitcoin Block Halving prediction
=====================================
bc=974613
gbt=1231006505
bbt=1793845038
This is average time to mine a block
(1793845038-1231006505)/974613
bts=577.4989205983086637376438
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 23:35:49 UTC 2028
-------------------------------------
Next palindrome will be 975579
predicted to happen at this time:
Wed Nov 11 13:15:01 UTC 2026
-------------------------------------
Current mining epoch number is 483.
The next fortnight happens in block
975744 and probably around this time:
Thu Nov 12 15:43:09 UTC 2026
