of course, we are not people who arbitrarily choose a wallet carelessly to save our assets. it's the same, we give money to people we don't know if we are careless in choosing assets. we certainly choose the ones we have recognized and we trust, even though now there are more and more crypto wallets available.
This kinds of act will really protect our assets, not being moved right away by some enticing offers, perhaps we will do our best to make sure our investment will be safe before considering offers that might be good,needs to be more careful as always.
