Are you trying to tell us to store our funds(Bitcoins) on exchanges? Because that's the only way I know you can convert Bitcoin to usdt. Except you want to use multi coin wallets like trust which I still see as unsafe and not reliable. Yes the transaction fees is a very terrible thing at the moment but we shouldn't let a short time issue create for us a long time wound( something we will remember for ever).
Don't store your Bitcoins on exchanges. If at all, not all of them. You can just keep a small amount of funds there just Incase of emergency especially in times when fees are very high. Its a method that might save you fees but you may end up losing your funds through such method.
I agree with you because even in the con version you still have to spend some amount of coin to although its not as much as you would when you do the direct bitcoin transaction but then in all storing on an exchange an really be detrimental in the long run for you as exchanges ha never been the safest as always said on this forum of which have been proven to be true due to the events and happens been mentioned both on the platform here and out there as stories we have gotten to hear from others in there experience, even platforms such as trust wallet can be considered safer than exchanges in some cases.
For the cases of emergencies its always best to have little funds in the exchanges, but it should be such that wouldn't be of great concern to you if they eventually get hacked and stolen because exchanges are usually very prone and are never reliable enough because it may be compromised some day and you may have to loose all your funds almost immediately.
