=====================================
Bitcoin Block Halving prediction
=====================================
bc=972349
gbt=1231006505
bbt=1792509620
This is average time to mine a block
(1792509620-1231006505)/972349
bts=577.4701650640201573507481
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 15:12:35 UTC 2028
-------------------------------------
Next palindrome will be 973379
predicted to happen at this time:
Tue Oct 27 12:33:34 UTC 2026
-------------------------------------
Current mining epoch number is 482.
The next fortnight happens in block
973728 and probably around this time:
Thu Oct 29 20:32:31 UTC 2026
