No. Not all, at least not from start. Just too many.
There are obviously a lot of projects with no substance, only to get money. This has become a problem and I see no good solution for it.
But there are also projects that wanted to get some money to start up: some got the money, some didn't, some used the money well, but most didn't. Some had success, some didn't. Some still have success, some are dead or dying.
Actually even the "honest" coins, with no ICO, IEO or whatever have also become subject of speculation, just because it's possible.
But isn't this something that also happens on stock markets and Forex?!
