=====================================
Bitcoin Block Halving prediction
=====================================
bc=950745
gbt=1231006505
bbt=1779578038
This is average time to mine a block
(1779578038-1231006505)/950745
bts=576.9906294636001623987900
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 19:20:42 UTC 2028
-------------------------------------
Next palindrome will be 951159
predicted to happen at this time:
Tue May 26 17:35:12 UTC 2026
-------------------------------------
Current mining epoch number is 471.
The next fortnight happens in block
951552 and probably around this time:
Fri May 29 08:34:29 UTC 2026
