=====================================
Bitcoin Block Halving prediction
=====================================
bc=950805
gbt=1231006505
bbt=1779620733
This is average time to mine a block
(1779620733-1231006505)/950805
bts=576.9991228494561456280250
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 21:49:20 UTC 2028
-------------------------------------
Next palindrome will be 951159
predicted to happen at this time:
Tue May 26 19:49:50 UTC 2026
-------------------------------------
Current mining epoch number is 471.
The next fortnight happens in block
951552 and probably around this time:
Fri May 29 10:49:11 UTC 2026
