I like Monero, still consider it one of the actual OG coins that is useful thats not Bitcoin. Find it weird he would be pro XMR and not like BTC. One entirely relied on BTC to be where it is now. Then again, like you said, I'm wasting my time trying to understand his reasons for that.
He must be 'happy' to see network going lower again this coming week.
There is no Monero without Bitcoin so definitely a weird take. It could be just one of many situations where someone chose to not buy Bitcoin early and now they blame BTC for it because of their own ego issues.
What do you mean by big here?
Is it surge of miners? or is it surge of tx because people are using bitcoin more frequently for something like sending money, etc?
If it's just surge of miners, the difficulty will adjust, basically nothing happens just higher difficulty.
Perhaps, the OP was referring to the Bitcoin network's transaction congestion, if so, then it is all about Blockchain Network Congestion, and this can occur on any blockchain network, including Bitcoin and other layer-1 altcoins. The answer is that when this happens, users experience transaction delays, and this is due to the large queues. Therefore, if we want to speed things up, we typically increase the network fee for the transactions.
For reference, maybe OP could read the explanation from anywhere (google, youtube, etc.), and one of it, is from here: -
What is blockchain network congestion? Yes blockchain congestion happens on many networks. It is alright if it happens sometimes, that's why you can pay higher fees if you need your transaction to be a priority. This is not a problem for now.
