=====================================
Bitcoin Block Halving prediction
=====================================
bc=863272
gbt=1231006505
bbt=1727566141
This is average time to mine a block
(1727566141-1231006505)/863272
bts=575.2057993241998765164669
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Feb 24 02:46:09 UTC 2028
-------------------------------------
Next palindrome will be 863368
predicted to happen at this time:
Sun Sep 29 14:49:20 UTC 2024
-------------------------------------
Current mining epoch number is 428.
The next fortnight happens in block
864864 and probably around this time:
Wed Oct 9 13:51:08 UTC 2024
