=====================================
Bitcoin Block Halving prediction
=====================================
bc=951270
gbt=1231006505
bbt=1779893256
This is average time to mine a block
(1779893256-1231006505)/951270
bts=577.0035573459087893986046
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 23:06:57 UTC 2028
-------------------------------------
Next palindrome will be 952259
predicted to happen at this time:
Wed Jun 3 05:18:32 UTC 2026
-------------------------------------
Current mining epoch number is 471.
The next fortnight happens in block
951552 and probably around this time:
Fri May 29 11:59:31 UTC 2026
