=====================================
Bitcoin Block Halving prediction
=====================================
bc=962371
gbt=1231006505
bbt=1786680866
This is average time to mine a block
(1786680866-1231006505)/962371
bts=577.4007982360251545140548
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 21 18:58:40 UTC 2028
-------------------------------------
Next palindrome will be 963369
predicted to happen at this time:
Thu Aug 20 20:18:31 UTC 2026
-------------------------------------
Current mining epoch number is 477.
The next fortnight happens in block
963648 and probably around this time:
Sat Aug 22 17:03:26 UTC 2026
