Everyone can manage his assets based n how he used how his playing to hold the bitcoins but I personally won't use any mobile wallet even the most secure wallets are always dangerous, the main reason is your phone can be vulnerable against many RATs, viruses and malware while there is also a high chance of losing your phone or someone may robe your phone on the street that's why I personally won't save any important information in the phone I use unless you have two phones and one phone can be dedicated only for bitcoin and cryptocurrencies and that's what I do. Also, I hold the bitcoin I want to hold for the long term inside another bitcoin wallet.
