Trust wallet is the wallet that I use to store all the altcoins I have so far, all of them can be stored there with one application, with that convenience it doesn't bother me to save too many phrase.
But the risk that you face is that if a hacker attacks, your property will lose everything. You better use multiple wallets, maybe 2 or 3 wallets and split your crypto assets equally. If unfortunately one of the wallets is hacked, the hacker can only get a small part of your assets, store it all in one wallet, convenient for storing private keys, but at risk of losing them all when hacked.
