=====================================
Bitcoin Block Halving prediction
=====================================
bc=950586
gbt=1231006505
bbt=1779493802
This is average time to mine a block
(1779493802-1231006505)/950586
bts=576.9985251218457647748180
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 21:38:53 UTC 2028
-------------------------------------
Next palindrome will be 951159
predicted to happen at this time:
Tue May 26 19:40:22 UTC 2026
-------------------------------------
Current mining epoch number is 471.
The next fortnight happens in block
951552 and probably around this time:
Fri May 29 10:39:42 UTC 2026
