Interesting your opinion about ETFs so no more bad news so the price rises... but if ETF were accepted the price would have rose also... in fact BTC will go to the moon whatever things can happen around 
in my opinion there is only one thing that matters for price rise and that is adoption. as long as more people are coming in and starting to use bitcoin the price will go up and having a limited supply helps with that rise too. but we still need the increased adoption. ETF isn't just some magic thing that can increase the adoption or prevent it which is why I believe its approval or rejection won't change much.Well, of course I’m quite a newbie in crypto, I’m in bitcoin only for 1year, so can someone tell me what can be the average of some up or down move in a day .. 100 or 200 $ or 10% - 20% ?
take a look at some charts and you should get a better answer.the change can be anything and we have had huge changes in the past. but usually it is not bigger than 10% per day which can be considered as a small change since bitcoin is already volatile. amount doesn't matter ($100, $200) because it is relative. for example if price is $10 and it goes up $100 that is a gigantic rise but if price is $100,000 and goes up $100 that is nothing because the first one is 1000% rise and the second one is 0.1% rise.
