probably a scam
qtum ceo = disreputable at best probably a scammer
allcoin exchange = scam
2 huge red flags
tim draper - hear that name everywhere lately so means nothing
allcoin seems to have had an ownership change, but everyone who had funds in the old was told to contact them with an email, so i am not sure its scam. now everyone screams scam way too easy. i saw hitbtc has 99% bad reviews but its mostly from people putting low transactions fee, or from some delays, but never actually from hitbtc stealing anything....... and when people get their funds they never change the "scam!" reviews..... its a bit frustrating for exchanges i am sure.
i dont know anything about qtum allegations..
as for spacechain and tim draper... well..... tim draper founded hotmail, skype and so much more .he is well respected everywhere....
the risk factor i see more in jeff garzik as he is not very focused it seems in general...
but he is only technical chief so maybe the 40 devs still work together nice

the ceo of spacechain is in his 20s and already had a very successful company in education. seems trustworthy to me.
biggest challenge is how big spacechain can get. such projects often fail because of low interest, low funds (because everything can be very expensive in space) but i do think spacechain got some nice solutions for it, like cheap satellites, and of course tim draper, plus a good mission and cause.
ALLCOIN = scam 100%
I know this personally giving people the run around saying they have no record of their accounts and shit when the people have the full email proof they had accounts there.
qtum ie stephen dai was found to be a part of the scammers that raped the bitbay ico. The full investigation was laid bare by gleb and david zimbeck spoke out about it too. He was not a prime scammer but still took BTC and contributed nothing to the project even when invited to do so. He is only not a prime scammer like the rest since he returned his bitbay to the real dev but kept the btc. If you want the full investigation you can find it on the start of the qtum thread unless they removed it.
those 2 are red flags but do not essentially say this entire project is a scam... but those 2 things... especially having to stoop to a shit hole like allcoin are bad news
