=====================================
Bitcoin Block Halving prediction
=====================================
bc=950808
gbt=1231006505
bbt=1779622592
This is average time to mine a block
(1779622592-1231006505)/950808
bts=576.9992574744244112119258
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 21:51:42 UTC 2028
-------------------------------------
Next palindrome will be 951159
predicted to happen at this time:
Tue May 26 19:51:58 UTC 2026
-------------------------------------
Current mining epoch number is 471.
The next fortnight happens in block
951552 and probably around this time:
Fri May 29 10:51:19 UTC 2026
