in my opnion,i think most people they don't care about scame or not,they just care money,so let thoess people buy shitcoins!
If I may ask, haven't you lost any money because of scammer devs at all?
I lost money in pure scams too but i took some lesson.
Most of all fails is GREED just call it correctly... - we have invested in most shitcoins because of greed...
After some time shit coin will have to die or try harder to live...
We will see how it will go over time.
Only time will shows winners but MANY coins till die over time.
About Big IPOs - Mastercoin was pumped to 90m market cap today is 3m...
Same can be with Etherum,Maidsafe,Bitshares...
There is no perfect solution just buy people smart and live with that coin can drop value over time.
I don't want to give my opinion about the "greed" part now. There isn't any TRUST in cryptocurrency community. Most of the time, you can't be sure if a coin is legit or not. We want to find a way to bring back at least a little trust to the community.
