It's my opinion that a lot of investors simply don't understand how mining works. If they did, then they would understand that AM hardware and shares are vastly overpriced.
Just like a lot of people paying silly money for mining bonds have found out, AM investors will come to the same realisation that share prices are currently way overpriced.
LISTEN AND LISTEN CAREFULLY. The only reason why AM is able to charge such outrageous prices is because they've had no competition. By the end of the year, there will be plenty of competition. Here's a quick comparison:
AM Block Erupter Blade
10 Gh/s
50 BTC = 5,000 USD @ 100 USD/BTC
2 Mh/s per USD
KNC Jupiter
350 Gh/s
7,000 USD @ 100 USD/BTC
50 Mh/s per USD
It should be blatantly obvious to anyone with half a brain that there's going to be a lot less income from hardware sales due to competition. That same competition will also decrease AM's share of the network hash rate.
AM share holders are going to get hit by a good dose of reality in the coming months. Perhaps then they will stop listening to idiots trying to flog them overpriced stuff and do the maths themselves.
