Hello, I'm looking for a trustworthy multi-currency wallet. Can you suggest me any? I've tried Exodus, Jaxx, HolyTransaction, Blockchain info. But none of them were able to hold my selection of coins. So by now my only option is to keep some funds on my crypto-exchange accounts. 

Do you know of a wallet that is compatible with a maximum quantity of various coins?

And one more question, if you don't mind. As for as I understand, all these wallets are centralized, wich means that the developers can get access to my funds, cannot they? If so, do you know of a decentralized multi-currency wallet?

Thanks in advance!
