Not 100%?
The selection on Havelock is 100% scam or, at best, simple fail.  Only two exceptions:  Matt's betting operation, (B.EXCH; B.MINE; B.SELL), and Branny's RENT (which is above IPO, most likely another pre-NthPO pump).  The rest selling way below IPO and/or ran.

For instance, Havelock swore up and down that it's holding 100 BTC in escrow for MintSpare (ticker:MS).  The issuer hasn't been heard from for half a year or more (longer than friedcat), the price tanked (much like here), and Havelock is ...doing what Havelock does best, ignoring & denying.
MS market cap, BTW, is vacillating between 6 and 12 BTC, substantially short of the alleged 100 held in in escrow by Havelock.
Not that Havelock's own ...offering, Havelock Investment Fund (ticker:HIF) is doing much better.  Nope, tanked hard and never paid divs

So yeah, somewhat less than 100% scam protection.  Especially considering recent past like Basic Mining & NeoBee.  Such concentration of fail being purely due to chance is nearly impossible.  Not unless Bitcoine4rs are an order of magnitude dumber & suckier @ business than regular people.
