=====================================
Bitcoin Block Halving prediction
=====================================
bc=973744
gbt=1231006505
bbt=1793309029
This is average time to mine a block
(1793309029-1231006505)/973744
bts=577.4638370415252453157654
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 13:21:51 UTC 2028
-------------------------------------
Next palindrome will be 974479
predicted to happen at this time:
Tue Nov 3 19:17:44 UTC 2026
-------------------------------------
Current mining epoch number is 483.
The next fortnight happens in block
975744 and probably around this time:
Thu Nov 12 06:12:36 UTC 2026
