There are several reasons that I could think of:
1. They don't want BTC to drop for whatever reason, maybe die-hard fans.
2. They want to liquidate the short on the margin market so they got profits as the majority are trying to short.
3. They don't really think about TA and stuff like that and just need to buy a lot of bitcoin.
Your who question is impossible to answer unless you ask Binance.
as i see from actions of these buys :
- these actions take all btc that is sold
- and important - these actions are keeping price at some level
so, as i understand, they want mostly to keep price, but for this they should also get all additional btc that is sold
what group of people is interested in this?
i roughly understand what they do, but i dont understand - who are they as group of people.
there is chart at link with sample how price is moved up after dropping down by sold volume
https://ibb.co/Kh22CY21 bar - 1 minute
time is - gmt + 3
to move price from 6770 to 6880 - was bought about 300 btc, that costs about $2 000 000
so some group for 30 minutes moved price up by $100 - by firing 2 mln usd for this.
Why they were fired - because when all are selling - they bought and move price up,
If they want just buy btc - they can buy btc that is sold - and dont move price up
so as i see - main goal of them - keep price.
what group of people want to keep price and have 600 mln usd per month for this?
of course, could be more groups of people
- first group move price up when all sold
- second group bought all btc that is sold
than question - what group have so $$$ that they can move price up and fire so $$ for this?
