Even if you apply all the tips from your list, you would still be stressed out about the crypto price crash, because your financial situation would depend on the current crypto prices. The cryptocurrency markets are very volatile and it's normal to witness big price dumps every now and then. It's impossible for the Bitcoin price to keep going up and up, without any price corrections and bear markets.
Not using the internet and staying away from online activities during a price crash seems like a funny advice, if you ask me.
This is why if you want to be a good trader, you should be aiming for a profit and most traders are not making that profit right now, because the market is down and many of them think that they are not going to do that fine. I believe that we should be considering this market crash as something benefiting us, because we could buy right now and make more profit later on, and newbies should be shown that and if they make a profit they would have more courage.
Because that way, stress would go away, there are two options, either you trade and make a profit, or you trade and it goes down and you buy more and hold long term and make a profit anyway. That's the way it should be and the stress would go away when you do that, it would benefit you and the profits will come. No matter how newbie or veteran you are, this method will make sure that your stress isn't too much and you end up with something good.
