Although I gave in and grabbed a few in the last week.
The way the pump works is the insiders buy from themselves to pump up volume and price, which causes jealous speculators to capitulate. They never buy back your coins that you bought from the insiders. Instead, you can only sell when there are more greater fools like yourself who are fooled by the pump of volume and price.
The true liquidity is probably less than $million (and thus true market cap is only a few $millions at best), and once the rate of new fools is less than those who want to take profits, then it crashes. Then they pump it up again buying from themselves and start the process again.
I believe this is actually illegal under SEC regulations because they are marketing this to USA investors. I will be researching this and posting about it another thread. I believe also this forum could be found culpable and if were Theymos I would make sure I had consulted an attorney.
Personally I wouldn't touch ETH with a 100 foot pole because of the potential of being tied up in some future mass investigation (not that would normally make sense but...). I fear the governments are going bezerk due to bankruptcy and they will use any excuse to tie people up in audits and other crap from 2017 onwards.
It just isn't worth it. Any one buying little morsels of a scam is just not very wise. If you are going to buy ETH you should be doing it large size to make it worth your risk, but then you should only risk what you can afford to lose and remember the insiders will not let you compete with them.
