For me not for Ukraine.
I have my corn stash on wallets I control, I have some corn for trading (no risk, just that as the price goes up, the corn is sold, so it's a given that at some point all that corn may be sold), and some corn for trying to earn corn in other ways. That last bit is probably too much, but I've reduced the risks I take, to a point. In January I got greedy, something was too good to pass up, with almost no risk, and I took from my stash to put into that "investment".
Things went wrong, not with the people involved, but the site crashed badly. There was also the police involved almost simultaneously.
Needless to say I slept badly for the past month and a half.
Now the site has come back, and the corn is back in my stash. I even reduced the usual risked amount and increased my stash, and will go back to hodl that without anymore exception whatever the offer !
You should use a DEX.
