=====================================
Bitcoin Block Halving prediction
=====================================
bc=929862
gbt=1231006505
bbt=1766925010
This is average time to mine a block
(1766925010-1231006505)/929862
bts=576.3413588883523701878663
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 8 21:58:28 UTC 2028
-------------------------------------
Next palindrome will be 929929
predicted to happen at this time:
Sun Dec 28 23:13:44 UTC 2025
-------------------------------------
Current mining epoch number is 461.
The next fortnight happens in block
931392 and probably around this time:
