Yes, this is a wise move. Everyone should have invested the amount that he is willing to lose. Of course, no one likes losses, especially so devastating, but right now, this is a great time to experiment a bit, or simply put your portfolio on a cold wallet. The bear market can stay here for a while and looking at these prices will not make you happy (if you are not buying, of course

). Give it some time and things can turn around in a surprising way.
Yes exactly, you got my point, and if one is not buying at the moment he should take a break but not necessarily selling out his portfolio because he is pissed with the market but with patience.
Just like what you mentioned about investing amount one is willing to lose, there is a thread I opened to explain it in detail you can take a look and add to it here:

But remember as long as the development of the related project is still active and it will be find to keep em all for yourself but remember there will always be a high risk will have involved in every moment.
