=====================================
Bitcoin Block Halving prediction
=====================================
bc=965923
gbt=1231006505
bbt=1788781745
This is average time to mine a block
(1788781745-1231006505)/965923
bts=577.4525117918179898211453
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 10:03:39 UTC 2028
-------------------------------------
Next palindrome will be 966669
predicted to happen at this time:
Sat Sep 12 11:28:44 UTC 2026
-------------------------------------
Current mining epoch number is 479.
The next fortnight happens in block
967680 and probably around this time:
Sat Sep 19 05:38:49 UTC 2026
