=====================================
Bitcoin Block Halving prediction
=====================================
bc=970413
gbt=1231006505
bbt=1791419782
This is average time to mine a block
(1791419782-1231006505)/970413
bts=577.4991673656810392265569
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 23:40:08 UTC 2028
-------------------------------------
Next palindrome will be 971179
predicted to happen at this time:
Tue Oct 13 03:29:06 UTC 2026
-------------------------------------
Current mining epoch number is 481.
The next fortnight happens in block
971712 and probably around this time:
Fri Oct 16 16:59:13 UTC 2026
