How is the price of an alt coin calculated in (for example) Bittrex? In BTC or in Dollar?
I buy alt coins in BTC from Bittrex, but is this BTC price calculated from dollars to BTC by Bittrex (combined with demand/ask), or are the alt coins standard defined / calculated in BTC? Why this question: as far as i can see, the price of a certain alt coin only changes because of ask/demand. I don’t see any change in the SAT price of an alt-coin when the BTC dollar price goes up or goes down (well, i haven’t noticed this so far as I can see this difference).
So if a certain alt coin (coin ‘X’) is worth 1000SAT and the ask/demand is steady (no fluctuation), what would happen to the dollar price of this coin ‘X' when the BTC dollar price will double from [X] dollars to [Y] dollars? Will the value of coin ‘X’ still be 1000SAT at price [Y] or will the price of this certain coin drop from 1000SAT to 500SAT because BTC-Dollar price doubled?
there are two types of altcoins, those that are only being traded with bitcoin (and possibly with some other altcoins) and those that on top of that they are also being traded with fiat.
the first ones are only worth in BTC
the second ones both BTC and FIAT (like USD for example).
the rise and falls of all these altcoins are usually independent from bitcoin, they are pumped and dumped most of the time so they don't care if bitcoin is rising falling or even dead
sometimes however bitcoin price affects them. for example when bitcoin is stable many traders move to altcoin market to make the profit they can't make in bitcoin because if its stability and when it starts rising again they pull out their money back to bitcoin and that causes ALTs to crash.
there are a lot of other scenarios that can happen too. mostly depends on which altcoin you are talking about.
...of BTC in the early days. Could it be possible that ‘they’ started to invest/take part in this journey a couple of years ago or even, worst case, in the beginning of BTC?
why do you even care? they may or may not have invested in it. why is it "worse case". many have invested in a lot of things, lets say Gold when it was cheaper, Apple shares when it was worth nothing, the list goes on, why should you care if someone else was earlier than you in investing in Apple and now has a lot more money?
the total market cap was around the 1.5 billion Dollars. Taking a large part within this market cap would be no problem for ’them’. Looking at the fortune of these families/groups, what could be the total share they could possibly have in BTC, looking at their fortune?
if market cap interests you then check how much bigger all the other market caps are compared to bitcoin then come back.
and again why do you assume someone has invested in bitcoin just to pull out suddenly and crash the market!!! that is not normal human behavior!
One collapse to destroy them all (financially)….
I think you are a bit confused about how manipulated altcoins with >90% of their supply controlled by a couple of people work compared to the well distributed and globally growing bitcoin.
