BTW in some sense, BTC is already inferior to many other newer blockchains
Factom is really a BTC/ETH app and inherits from the security of those 2 blockchains.
XEM would be better IF its security was equivalent to BTC which it has no chance.
I rearranged your post a little to analyze it. Can you clarify your argument as to why NEM isn't as secure as BTC and which alts you consider superior to BTC?
XEM or really any other blockchain today isn't as secure as BTC because the tiny size of their network make it vulnerable to things similar to 51% attack...
detractors of BTC would point out that a lot of BTC nodes are in China, which is not a good thing either.
on the specs side, XEM and many other blockchains are superior to BTC.... XMR has stronger anonymity, ETH has smart contracts, etc...
u should be very careful to make such a statment
how many fullnodes bitcoin network have
how man different nodes produce 80% of the blocks
how many fullnodes NEM network have
how man different nodes produce 80% of the blocks
u would be surprised how deepend bitcoin blockproduction is towards 5 top mining pools
and most of them in china
bitcoin decentral?
mining all around the globe secure it?
what a illusion
bitcoin is full in chinese hands
a deeper analysis will show ya that the nem way secure the chain is superior
and if bitcoin chain is the only advantage u think factom have above NEM apostille
then u should question urself whats the true holy grail here.....
or a bit less black white
if they not at least similar interesting solutions
FCT for sure have a advantage by already established contracts
but from technological view NEM apostille is a solution that is equal powerful
and simpler in complexity
and
simple is beautiful
