Does volume cause the pump? Or does the pump cause the volume?
The pump causes the volume DAAAh, it this would not matter if its authentic pumping of domestic news of the coins wiht a new feature or a new update, or from pump groups, a pump is a pump. Without someone pumping a coin, there is no additional attention being drawn to that coin, without people pumping it no one knows whats going on, when people hear about a coin pump and see it being pumped, they buy in, when they buy in others follow the leader like monkey see monkey do. thus.... The pump causes the volume, because without the pump you just have regular everyday price action.
+1 I agree with everything your saying here
in the group we like to say that the No.1 performing asset in crypto is the PUMP
If your looking for a winner just bet on the pump and you shall be victorious

But on a more serious note theres some things you said that don't add up
UNDERSTAND THIS, Crypto has no "REAL" demand, no one has to buy any crypto for a purpose, there is no product that can only be purchased with crypto, there is no service offered by way of payment with crypto only, their are no places that only accept Crypto, there is no country in demand of using the crypto, THERE IS NO DEMAND, the only thing that gives a coin its value is it tradable market, the exchanges and who is buying what when.
Everything your saying here is way off the mark
Is there any "real demand" for apple or google stock? Do people really "need" to own shares in facebook or ibm?
Of course not but they buy anyway
so maybe you have gotten some wires crossed there because you seem to be using the word demand incorrectly
Porn is one of the most addictive hobbies in the world and that is why they made so much money back in the day before the invasion of the tube sites.
Do people "need" porn? of course not! but they do need sex. so porn is just a means to an end.
Porn capitalizes on the "need" for sex, theres your demand
You are right though in saying there is no "need" for altcoins because that is totally true, if altcoins were to dissappear tomorrow the world will keep on turning
but for us in the alt market, altcoins are just a means to an end
we know that we can buy an alt, convert it to btc then cash out dollars. So the "demand" is actually for usd gbp eur etc not the alt itself
altcoins are just a means to making money and THAT is why people buy
that is how pumps actually work, they create demand for a coin and people buy because they think they can make money quickly (usd gbp eur) there is demand for fiat and altcoins are just a means to generating more fiat
theres your demand
if there was no demand like you say then no one would buy anything, there wouldn't even be a crypto market
