=====================================
Bitcoin Block Halving prediction
=====================================
bc=974157
gbt=1231006505
bbt=1793554692
This is average time to mine a block
(1793554692-1231006505)/974157
bts=577.4711976907236813740686
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 15:30:40 UTC 2028
-------------------------------------
Next palindrome will be 974479
predicted to happen at this time:
Tue Nov 3 21:17:17 UTC 2026
-------------------------------------
Current mining epoch number is 483.
The next fortnight happens in block
975744 and probably around this time:
Thu Nov 12 08:12:18 UTC 2026
