Right now we have 257,293 Tx unconfirmed at the moment. And the fee is also decreasing. Getting 50 Sat/vbyte is much better than getting 200+sat/vbyte. Also if the ETF is not approved today on friday, then we can have even lower fees during this weekend. However if ETF is approved, then mem pool can again become congested due to lot of transactions.
Right now have decreasing with bitcoin transaction and take only 50 Sat/vbyte for sending bitcoin from one wallet to other wallet, my sending last several days have been landed well after decreasing of lower fees transaction and its take more than three days before receiving in my bitcoin wallet. For ETF approved or not I don't get accurate information because have rumor is fake news and bitcoin drop drastically but we get benefit with fees sending of bitcoin decreasing drastically and use lower fees transaction just take about twenty minutes only.
I don't think in the future have potential with fees transaction for sending bitcoin will up again above 150 Sat/vbyte despite ETF approval or not, if you have bitcoin assets in wallet its right time for depositing in exchange account if you want to sell it and save in one wallet if you hold bitcoin in several wallet due with lower fees, faster transaction not make difficult later when selling bitcoin in the market.
