This is a big reason I'm considering these two options.
Coinbase is fairly well respected for being secure and their crypto-assets are insured so I'd feel relatively comfortable using them.
Plutus is by far the most secure option out of them all as you attach your personal wallets rather than trusting them with your crypto, they're never in possession of your assets so company hacks are impossible. They also use a decentralised exchange to facilitate spending so no worries there.
I don't think I'd feel comfortable using Wirex or Bitwala tho, not sure how secure they are.
