=====================================
Bitcoin Block Halving prediction
=====================================
bc=949536
gbt=1231006505
bbt=1778860884
This is average time to mine a block
(1778860884-1231006505)/949536
bts=576.9700169661635091628867
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 13:19:59 UTC 2028
-------------------------------------
Next palindrome will be 949949
predicted to happen at this time:
Mon May 18 10:12:52 UTC 2026
-------------------------------------
Current mining epoch number is 471.
The next fortnight happens in block
951552 and probably around this time:
Fri May 29 03:07:35 UTC 2026
