Good day everyone,

since the collapse of FTX we had many discussion about people withdrawing their Bitcoin from exchanges. You can check the balances here https://www.coinglass.com/Balance.
We went from 2.1 million BTC all the way down to 1.9 million BTC.

Until yesterday Binance was one of the biggest looser with over 80k BTC withdrawn over the last 30 days. Coinbase was ranked first, but also with massive loses. Nearly all exchanges lost huge amounts, fitting perfectly in the narrative of people withdrawing their bitcoin.

But suddenly in the last 24 hours Binance added and incredible 92,000 Bitcoin to their exchange an amount never seen before on the exchange (according to coinglass, and if you check the last 12 months). I found very little info about that, and all nearly other exchanges are still getting their balance reduces.

Do we have some info about that or any idea whats going on?

[What does it mean for the mempool to be "full"?]

According to https://mempool.space/docs/faq:

What does it mean for the mempool to be "full"?
When a Bitcoin transaction is made, it is stored in a Bitcoin node's mempool before it is confirmed into a block. When the rate of incoming transactions exceeds the rate transactions are confirmed, the mempool grows in size.
The default maximum size of a Bitcoin node's mempool is 300MB, so when there are 300MB of transactions in the mempool, we say it's "full".

It explains how we got there, but doesn't elaborate on what that means for Bitcoin.

Right now we are at  354 MB / 300 MB, but if that doesn't have any effect why are we even talking about a limit in the first place?

Greetings,

I got a few questions regarding the way how miners choose transactions.

1. While a miner hashes, will the nonce be reset on every new transaction added to the block?
2. And if blocks are not full, are new transactions added instantly or is there some sort of "waiting time"?

Best regards
