when the market goes down, I just suggest that you stay calm. because I'm sure the market won't forever go down. unless you are in a state of really needing money. therefore if in my opinion do not invest all of your money so that when prices go down you can still hold and life continues.
Markets often go up and down, really bad in conditions like this do make everyone experience panic. as you say eliminates panic and you have to be calm, if you panic, you will make the wrong decision. if you don't want to experience losses you have to endure to temporarily hold the coins you have, until the price is really stable
