I have used trustwallet for about 2 years and in my opinion is safe, but I have read the article that multi platform wallet by providing seeds is in accordance with the programs designed so that all the seeds are also owned by developers, true or not this of course we must always be vigilant.
Most wallets have that kind of issue. I have been using Trust wallet for over 3 years now and I can say that it's really trusted.
However, we can't take all our doubts away so I still store my funds on a hard wallet where I could feel more comfortable and confident while keeping my investment.
Trust wallet has a good trust rate compared to other wallets and it's safety as for me depends on how we keep our keys and access safe.
Trust Wallet is a good, safe, and easy wallet for all investors. I can hold a lot of altcoins on it, most of which may not be in the hardware wallet. For me, the thing that worries me is that Trust Wallet is owned by Binance, and if something happens to Binance, this wallet will also be damaged, so hardware wallets are the best, It is not free, but in return for purchasing it, you will have a higher security rate than any other wallet, so you can sacrifice some dollars in exchange for living with peace of mind and not losing your money one day.
Therefore, if you would like to use hardware wallets, this will be the best and safest for you, you can buy the popular cold wallets in the market from their official websites.
