=====================================
Bitcoin Block Halving prediction
=====================================
bc=950811
gbt=1231006505
bbt=1779624444
This is average time to mine a block
(1779624444-1231006505)/950811
bts=576.9993847364147696915899
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 21:53:55 UTC 2028
-------------------------------------
Next palindrome will be 951159
predicted to happen at this time:
Tue May 26 19:53:59 UTC 2026
-------------------------------------
Current mining epoch number is 471.
The next fortnight happens in block
951552 and probably around this time:
Fri May 29 10:53:20 UTC 2026
