every time someone put a doubt about posa and cloak you stayed very offensive and mad. This is not a good feeling for you. You don´t demonstrate anything until now. Who is the kid here? I just put some questions in the air and you should answer with true demonstrations of the poSa working.
I'm sorrry. Sometimes people are not behaving very grown up here - maybe they aren't (grown up)!
I think you, as a potential investor, have all the right to ask questions about PoSa and everything. In fact every potential investor should be asking these questions. And personally I think, what you are saying and doubting makes sense, of course it does. There has been so many delays etc. on the way.
Until PoSa is released, we have no hard evidence of anything. Regardless of, if somebody said he heard somebody, from a friend's friend, testing PoSa, or broadcasting some irc chat... it's all hearsay.
Therefore: Based on speculation, right now you can buy Cloak for this price. If PoSa fails, or is not delivered in the very near future, you almost sure lost that money. However, if the devs deliver a working PoSa, then you will triple...or who knows how many times make your money back. This is risky, but sometimes early birds get the prey.
Do your own math. Maybe for you, the wise thing is to buy a little bit Cloak, say 0.5 btc, to be on the safe side? You call your own shots.
Personally I am 100% in. What convinced me was one of the devs (x11joe), who answered one of my tricky questions very fast and very well..
This has the potential to be the game changer... and If this doesn't work out, I am calling it a day, and probably will leave crypto for good, and will find other pursuits of interest. That's how high my stakes are here! whew. Good luck with all!
