Let me first say that this is just my own opinion, not the one of others. I am not trying to spread fud, I am just one miner, do what you want with my message... but here is a copy/paste of a post that I made on the Sparks coin thread a few days ago... My suspicions are getting more serious since, those always anonymous developpers are getting more and more silent, and I feel it is important you research this:
Sparks, Rapture, Phobos, Cerberus, Crowdcoin, Race, Dinero, Infinex, Force, Stipend, Endorphin, VIVO, Innova, Cropcoin and the list goes on and on and on.... All the same exact pattern copied: Masternode/PoW hybrid, ''small'' premine, Masternode auctions through discords, Airdrops , Anonymous teams, same wallet code and bugs, Masternode gets most or half of the mining, only on stocksexchange (except 2 or 3 of thoses)... It wouldnt surprise me if it would be all coming from the same team/person or maybe a teacher somewhere giving his students a school project to each start a coin... Extremely suspicious, do your research and prove me wrong please!
It's not FUD if its the truth, there are a worrying number of faceless and nameless dev teams pumping out projects with big claims at a high rate. I decided a while ago to steer clear of these kinds of coins
