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 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.
