I'm thinking about trading altcoins as in buying a bunch of altcoins when prices dip a lot. Then sell them when the price goes back up. I found out if you want to trade altcoins, you have to use btc to do this. Now if i want to trade btc, how do i do that? Wouldn't that mean trading btc for usd or tether? For example someone mentioned btc was like 4700 but then it started dipping a lot and he sold all his btc like at 4500. Then it dipped all the way down to like 3200 or so. Then he bought all the btc he sold for around that price etc.
as long as you have btc in your balance, you can trading btc for usd/tether. and the result is you have altcoin, btc and tether in your balance account.
in you case, you already sell your altcoin and now have btc, then you can trade btc pair fiat. but if he is buying btc at $4700 and sold all btc at $4500, this mean he is loss. but he might have a chance by buying again at $3200 and hold it for a while because the price will be up again.
So if someone does this, that means they are selling their btc for usd or tether right? What im curious about is if they sold all their btc at 4500 and then bought them back again at 3200 or so, where does the profit go? Usually in their bank account or USD balance? Or do they buy more btc? For example say someone has 5 btc. Sold 5 of them at 4500 for 22500. Then if they buy back 5 at 3200, thats around 16000. So here they make 6500 profit but do people like this just buy back the btc plus more? So instead of owning 5 btc, they have like 7 btc because of this?
first they are loss because they sold at low price. but if somehow they can buy at low price $3200 and he is patience to see the price is more than $3500, then he can make profit. their balance is only on the exchanges and its not related with their bank account.
but its different if they deposit their money again to buy bitcoin at $3200.
in your case, someone has 5 btc and sold 5 btc at $4500. if he can buy back 5 btc at $3200, its mean that person have 5 btc + $6500 (this number is from $22500 - $16000 because he can buy bitcoin at $3200). i hope you are understand.
