Who cares if Monero and Dash are scams when you can make good money on every pump and dump.
Scammers take capital out of the ecosystem and spend it on crack, Yachts, booze, and prostitutes.
You personally may get richer (if you are a good speculator), while on average the ecosystem gets poorer, unless of course we are bringing more new fools (and their capital) into our ecosystem from outside of it.
So eventually there could be no ecosystem remaining for you to speculate in.
My opinion is we have a window of time (5 - 10 years?) within which to leverage this opportunity to produce something really significant that could help the world. And to produce a $trillion marketcap.
Any way, please continue what you are doing. Hopefully those who developers who are serious will find a way to operate within this ecosystem so we don't lose the potential.
