=====================================
Bitcoin Block Halving prediction
=====================================
bc=951058
gbt=1231006505
bbt=1779759989
This is average time to mine a block
(1779759989-1231006505)/951058
bts=576.9920520178033118870648
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 19:45:36 UTC 2028
-------------------------------------
Next palindrome will be 951159
predicted to happen at this time:
Tue May 26 17:57:45 UTC 2026
-------------------------------------
Current mining epoch number is 471.
The next fortnight happens in block
951552 and probably around this time:
Fri May 29 08:57:03 UTC 2026
