Dash is certainly not a scam but there are some users posting in this thread claiming that was a scam when it started out and
some claim to some degree it has scam-attributes because of the voting power masternode operators have with regards to the direction Dash will go down because of them playing a role in the key decision making process. Dash is no scam.
Actually,i am not a Dash fan. But i find it somehow inaccurate to judge the value of a coin only by its price in the market. If you invested in Dash few years ago then you should now become a millionaire after the 2017 crypto boom when the price of Dash surpassed 1$. The opposite would apply if you bought Dash at that ATH price.
I don't think that Dash is a scam or a plan to scam anybody even i have other critics over it.
As it will go down caused by its centralised nature, any investment in Dash is so risky. And we don't hear about updates to adjust the masternode power controlled by few parts.
Not only in this thread, i read from many reputed members here that Dash isn't even a cryptocurrency and somehow it's a system established by banks to keep generating profits from the new technology.
