=====================================
Bitcoin Block Halving prediction
=====================================
bc=951210
gbt=1231006505
bbt=1779853391
This is average time to mine a block
(1779853391-1231006505)/951210
bts=576.9980435465948143997493
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 21:30:27 UTC 2028
-------------------------------------
Next palindrome will be 952259
predicted to happen at this time:
Wed Jun 3 03:51:01 UTC 2026
-------------------------------------
Current mining epoch number is 471.
The next fortnight happens in block
951552 and probably around this time:
Fri May 29 10:32:04 UTC 2026
