You just don't invest to "coins" like btx or sigt.
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.
Bitcoin has got segwit since the bitcoin cash fork.
Maybe you are talking about 2M blocks...
