1.weird, ive been trading bitcoin for years and never had this problem(you don't even have to take my word for it, ive traded multiple times with your buddy opticbit, before i distrusted and blocked him this afternoon based on his association with you).
Occassionally interesting altcoins, too.
I gotta wonder what the point is of having a distrbuted ledger that isnt accurate... The whole point of crypto is you send a transaction and the transaction is sent, with a public record and everything.... thats the whole point theres none of this "check is in the mail my sla is 24 hours" nonsense.
that said, i got the facts, such as they are, directly from your coworker bill (im sure you can confirm with him) . These are his exact words: " sometimes [transfers] go through, sometimes they have to manually get sent againn. so it isn't a surprise that for a single user, a transfer will work, then a few seconds later another transfer wont, or vice versa."
Now ill admit that he never specified any particular percentage failure rate, but i dont think youd find very many people aside from 
2.No, it wasn't a pause during the security incident. It was two pauses during two security incidents. Im just specifying this because i want to make sure all the facts are straight, per your request. You can justify it however you like, but by the numbers, even ignoring the whole "5%" thing, youve had 50% uptime. I have an atari 800XL that does better than that. .. which brings me to
3.Isn't cutting edge technology supposed to preform better than regular old normal technology, not worse? Like, you don't hear people saying "Hey check out my new ferrari its a cutting edge car. It only works 2 days out of 4, and 5% of the time when it is working it explodes when you turn on the headlights." thats not cutting edge, thats just cut-up. Thats what i love about tech people show them any bug and theyll try to sell it as a feature.
