Ok ,im going to wade in here.
First off, "Whats different about this coin?" is a fairly unqualified question. One may well ask, whats different about pounds sterling, or US dollars, or Swiss Francs. Well, nothing. They're all bits of worthless paper, backed by nothing and manipulated by the private banking system via interest rate policy, qualitative easing (mining if you like) and hypothecation (creating money out of thin air).
So, whats different about RUBY compared to what - other crypto currencies? Er, well, the answer is obvious. Compared to SHA coins? Different algo. Compared to life span of other coins?
Regarding "pump and dump" - i have a bug bear about this so let me get it off my chest. It seems common place in crypto to even ask "when is the next pump and dump [so i can make some money]" Ive even seen new members of coin communities blatantly ask this question. In the real world, pump and dump or price manipulation will land you a custodial sentence. But also, consider what it is to "pump". Many seem unaware that to move a price up, someone has to spend a lot of money. The assumption that someone will do this just so you can take advantage is absurd. When asking "when is the pump and dump" is akin to asking "hey, when is it convenient to steal money from you". Just stop it.
Further, accusations of price manipulation is serious in the "real world", and in the real world there is a thing called "proof of claim" when the claimant (one calling "pump and dump") needs to bring proof. So, that being said, if you have proof, Id like to see it. Akin to making accusations is the "leading question". So, have YOU stopped beating your wife? Can you prove you've stopped? Well, i dont believe you until you prove it... you wife beater.
"Fake volume" - this is a strange thing to say, as a trade is a trade. Volume is volume. Whether this is generated by the actions of many buyers and sellers or bots is largely irrelevant. Again, in the real world, 'high volume' was a problem when HFT came into fashion. Its called a "free market" for this reason. Anyone can buy all the stock in two minutes and then sell it for profit at their leisure. This is one of the risks of IPOs and taking companies public... Volume is better than no volume? Brings liquidity no? Now, you might argue about MFI (high price moves on small volume as floor traders take inventory, but im not sure thats possible on crypto)
And finally on a minor point, and again in the "real world" when investors want to have a meeting with the project leads, they book a time and place, maybe sign NDAs, enter into a dialog and so on. The savvy investors watch the project lead for some time before even doing this. Imagine the investor who turns up unannounced, unqualified (in terms of intent and interest) at your place of work, sits in your meeting room and then DEMANDS his questions be answered. You'd probably ask him to leave.
And one final thought: when "you" (whoever you are) says "stay away from this [investment/coin/whatever] you ARE giving investment advice" - are you regulated and licensed to do so? If so, please leave your insurance number below such that I can make a claim in the event "your" advice is wrong.
^^^well said!
