=====================================
Bitcoin Block Halving prediction
=====================================
bc=950408
gbt=1231006505
bbt=1779394843
This is average time to mine a block
(1779394843-1231006505)/950408
bts=577.0024673587897421005062
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 22:47:52 UTC 2028
-------------------------------------
Next palindrome will be 951159
predicted to happen at this time:
Tue May 26 20:42:51 UTC 2026
-------------------------------------
Current mining epoch number is 471.
The next fortnight happens in block
951552 and probably around this time:
Fri May 29 11:42:13 UTC 2026
