My take on KAYI... I take a look at every other similarly priced coin out there, LDOGE or FFC for example, and see the same situation basically KAYI is in. No active development, no updates, low price. What is the difference between them and KAYI?
Someone is accumulating millions and millions of KAYI... which makes sense if you are a developer behind the scenes. You keep quiet, the price drops, you and your friends buy. You make an announcement or a release, the price increases. Have you noticed, even in this down market, every time the price drops to 5 or 6 sats lately, it quickly bounces back to 10? There is someone buying lots of KAYI.
What possible reason would anyone be buying based on the information we have in this Bitcointalk thread? None, so the only explanation that makes sense is someone is buying because of information not here in this thread.
So what's a realistic price for KAYI? Who knows, people have made outlandish predictions of 500 sats to 1000 sats... let's say if there is an announcement or update the price goes to just 50 sats, which I think is reasonable to expect. That means a .2 BTC buy now at 7 sats is worth 1.4 BTC, and if KAYI drops to 4 sats instead you lost less than .1 BTC. If you have a little BTC available, it seems like a reasonable gamble compared to some of the other schemes out there.
X2 Real talk- it's not a matter of trust or belief in the project enitrely. When most people look at a coin so cheap and see all the "home runs" in the crypto space they simply speculate on whether or not a throw away investment could yield big results. It's a throw away. Others see it as an opportunity to flip for some high percentage gains and maybe keep flipping. Even less see it as a potentially viable idea and may be interested into buying into the dream. Finally, there are smallest minority- those that are actively attempting to manipulate the price as gjsteele pointed out. I'm a reasonably seasoned investor and still toss a few dollars at stuff like this. It's like buying a lotto ticket with hopefully better odds.
