=====================================
Bitcoin Block Halving prediction
=====================================
bc=950365
gbt=1231006505
bbt=1779365001
This is average time to mine a block
(1779365001-1231006505)/950365
bts=576.9971737204403356180671
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 21:15:14 UTC 2028
-------------------------------------
Next palindrome will be 951159
predicted to happen at this time:
Tue May 26 19:18:56 UTC 2026
-------------------------------------
Current mining epoch number is 471.
The next fortnight happens in block
951552 and probably around this time:
Fri May 29 10:18:16 UTC 2026
