why many of so-called blockchain projects these days are scammers, is this was motive behind the technology? many real investors are not confident to participate due to fake blockchain projects all over the internet.
what are your views
You are relating two different things. \
Majority of blockchain projects have lost focus because either they weren't scalable enough or didn't make much sense in terms of utility. There were hundreds of projects coming every month. Not all can make it big. Although everyone was trying to tap on the opportunity.
Regarding scammers bringing fake projects. That is a different problem. Any new technology has this disadvantage. As people are relatively less aware. So, scamming them becomes easy.
The focus on blockchain projects is pretty much still there but only the worthwhile ones.
