Gulden is by far the best.
In about 24 hours Guldens blockchain will become the new standard in blockchain tech.
PoW2 - Witnessing PoW blocks which will make Gulden harder to attack then bitcoin and litecoin and witnesses get rewarded for being witnesses. It also makes SAFE 1 confirm transactions possible.
SegSig - 58% saving on all transactions, more then twice as good as SegWit.
Top 5 developer in the crypto space Malcolm Macloed.
What they haven't done is hype or promote Gulden like the scams and con artists are doing which explains the low marketcap but make no mistake the Gulden blockchain will be way ahead of the top 50 as of tomorrow.
