Over the past many months, which are there more of:
* New people who have heard of ethereum after the IPO and want to invest
or
* People who invested in the IPO but became frustrated with being unable to touch their money for so long and now want out.
Most of the IPO coins that I have seen either tank upon opening, or have a short pump and then tank. Bitshares first tanked in July when it was released, before the august pump.
I expect Ethereum to do one of those things. Its not going to be a fully formed product at release, and it had plenty of hype in the IPO. It should have both pumps and dumps like any coin.
I think it will be a great buy at points where it has suffered from dumps and everyone is depressed.
You shouldnt buy hype in crypto. Buy a coin when it is very unloved, sell if people get really excited about it. Buying bitshares after the august pump was bad. Buying when it was low in July, or now, is probably good.
