57 51% Attack?

58 More powerful than the tread of mighty armies is an idea whose time has come. ~ Victor Hugo

59 Alternative Coins MAJOR: -BTC Bitcoin - first, strongest, most accepted, most mined, high volume market, a true currency -LTC Litecoin - second only to BTC, faster than BTC, Smaller efficiency gap between GPUs and CPUs, ASIC-hostile -NMC Namecoin merged mined with BTC, used for alternative p2p domain system -PPC PPcoin Proof Of Stake [very innovative, low energy ], compatibile with BTC miners MINOR: -TRC Terracoin based on BTC, fast difficulty adjustment, initialy flaved but corrected -DVC Devcoin merged mined with BTC, 90% of generation goes to foundation, 10% to miners -IXC IxCoin merged mined with BTC, premined 580k coins but still alive -NVC NovaCoin - scrypt hashing[like LTC], proof of stake [like PPC], controversial start -FRC Freicoin - back alive. 4.89% anual demurrage. for the first 3 years 80% block subsidy goes to foundation, 20% to miners -FTC FeatherCoin- LTC clone with 4x more coins. CANDIDATES: -BTE Bytecoin- the 1:1 bitcoin copy, nothing changed. extremally high starting hype/hashrate. -BQC BBQCoin- forgotten after 51% attack on launch, now revived and active. super fast version of LTC. -MNC Mincoin- similar to BBQ, but very bad launch [no binaries % superblocks] giving 10% of all coins to insiders. -CNC CHNCoin- similar to BBQ, announced on chinese forum first, very big hashrate. -BTB BitBar- scarce version of NovaCoin. low starting diff like FTC and CNC, but quick adjustment. -JKC Junkcoin- started as a joke, but now working ok. low starting diff and slow retarget like BTE, FTC, MNC, CNC -YAC YACoin- Yet Another altCoin. NovaCoin fork, with modified hashing - for now CPU-ONLY -RYC Royalcoin- Another LTC clone, starting with low diff and superblocks like MNC... -FRK Franko- Another faster LTC, again starting diff. scarce. DEAD / DYING : -FTC Gamecoin- yes, FTC. clone so bad it was 51%'ed the first day. -LQC Liquidcoin made to be very fast at constant difficulty, dead [pool closed, exchange closed] -SC Solidcoin - dying (10-20% fee), designed to improove IxCoin, hard to be neutral on this one, 1.0 was a premine scam, 2.0 says BTC is pyramid scheme. The idea is out. Even if a fatal flaw is found and exploited in Bitcoin, a better version will emerge within 24 hours.... probably within 1 hour.
