Made a move yesterday after coming across few threads about coinomi wallet in wallets thread of this forum, missing funds, stolen recovery seeds, some said it's coinomi team, some blame SSL but I don't want this to happen to me, I finally switched to Trust wallet even though it's not fully open source, I hardly heard anything bad about the wallet.
I guess you could always have one on your own computer you know that right? Bitcoins original wallet is still there if you are wanting to get a bitcoin wallet, if you want altcoins you could literally have their original wallets there as well. If you want to own any coin you want, they do have wallets that you can download and having it on your computer with some back up would basically be the greatest defense against hacking ever.
You could also use hardware wallets as well, those are pretty much as guaranteed as it gets, plus they are pretty easy to use as well and they have a lot better UI too and look awesome. Both of those options are always better compared to any wallet you want to use, maybe they could sound harder but believe me they are quite easy as well when you get used to it.
