Sigt was just another POS scam. But bitcore (btx) is different.
Bitcore is a 1:1 replica of the bitcoin blockchain with a gpu friendly POW algo, and segwit included. Active dev team.. In my opinion bitcore should be priced higher than bitcoin gold and can go +300% or more in just a few weeks.

We all know that the seqwit fork of bitcoin was cancelled, but bitcore have had this functionallity for months already.

bitcore vs bitcoin gold

$32 vs $140




time will tell.
