Good that you mentioned this, someone also told me about trust wallet, recently it was found out to be using a security audit by a fake company and they market themselves as open source while in reality they have just pieces of old code on github and the android version is fully closed source (they even deleted their btalk thread when it was brought up). This time, through reading and finding good reviews about wallet, I came to know about Hodler wallet. So far, it works fine for me. It is also opensource and only multiwallet available. What do you think about it?
I'm not sure about trust wallet's security, but all I know that it's affiliated with Binance. So it somewhat has some reputation. I wouldn't risk it though.
I personally don't have an idea on that "hodler" wallet. For now, I would suggest sticking to the reputable wallets. I suggest trying out Exodus[1] if you're looking for a software wallet that can hold multiple cryptocurrencies.
If you're holding significant amounts of cryptocurrencies though(probably more than $1000 worth), I heavily suggest grabbing a hardware wallet like a Ledger Nano S[2] or a Trezor[3]. I can't stress this enough. Don't keep your huge amounts of crypto on a device that you frequently use online. Better safe than sorry.
