I use exchange wallet like binance and luno for cryptocurrency trading only. I do not like to use them to hold any cryptocurrency to inability to have access to your private keys or control of your wallet.
I open some wallet in the past but the most platform wallet that I use most is the one of binance so I don't have any other top three wallet again since am not into any fraudulent act.
I sent all my coins to binance from trust wallet after finding out that I used to forget them and not monitor their prices and this makes me to lose whenever there is a pump in prices.
When raking things like a crypto wallet we all have varying and diverse opinion well for me I'll rank mine as blockchain as first followed by binance and lastly trust,just because I have tested and actually used them.
you will not be able to trade on trust wallet that's just the issue, trust wallet is for holding of cryptocurrency for long-term investment,some people will just buy a potential cryptocurrency and lock it up in their trust wallet and deleted the trust wallet, they comeback in few years time to reap the full profit.
Some of these long term investors usually forget their twelve phrases key that would enable them access their coins. This leads to complete loss of everything they had.
My top three are binance, bitmex and trustwallet for now, reason i said for now is because i will add more wallet as long as i have more knowledge of crypto.
A lot of them do forget about it but that is not always intentional,maybe they write it down in a book and the book got lost or maybe because of one reason or the other they do not have access to it again, one of the worst experience.
