=====================================
Bitcoin Block Halving prediction
=====================================
bc=950416
gbt=1231006505
bbt=1779398214
This is average time to mine a block
(1779398214-1231006505)/950416
bts=577.0011573867049937027641
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 22:24:57 UTC 2028
-------------------------------------
Next palindrome will be 951159
predicted to happen at this time:
Tue May 26 20:22:05 UTC 2026
-------------------------------------
Current mining epoch number is 471.
The next fortnight happens in block
951552 and probably around this time:
Fri May 29 11:21:27 UTC 2026
