I present to you a new Bitcoin "Big List" style site.
The Big List of BitcoinThis site will be a great resource for new users starting out in Bitcoin to find reputable and trustworthy sites to use.
The site will be constantly updated, by me. This will be my long term project, it will stay up indefinitely.
Mt. Gox was hacked several times.
Bitfloor was hacked and lost everything.
MemoryDealers and Bitchain.info were implicated in the latest privacy breach issue.
Virwox, BTC-E, bitcoin.de and bitcoin-24 have been mentioned in threads of the "company" not doing their job several times.
Cryptostocks is a unregistered stock exchange destined to go the way of GLBSE real soon now.
Yes, but Mt.Gox and Bitfloor has stood behind their site and never made their customer lose money (some mtgox hacks were the fault of the customer losing their password, not mtgox's fault). They have learned from their mistake and made their site more secure, which is good.
Simply being complained against does make them not reputable. Even the most reputable companies has had complaints filed against them numerous times.
Cryptostocks will be gone or not, I can't predict. As of right now, it seems to be in good standing and growing popularity.
