=====================================
Bitcoin Block Halving prediction
=====================================
bc=950169
gbt=1231006505
bbt=1779242471
This is average time to mine a block
(1779242471-1231006505)/950169
bts=576.9872401780733973920456
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 18:21:24 UTC 2028
-------------------------------------
Next palindrome will be 951159
predicted to happen at this time:
Tue May 26 16:41:28 UTC 2026
-------------------------------------
Current mining epoch number is 471.
The next fortnight happens in block
951552 and probably around this time:
Fri May 29 07:40:44 UTC 2026
