I strongly advise against using Cryptonator! You can also read my blog post about Cryptonator SCAM Site: https://steemit.com/cryptonator/@aritmethos/cryptonator-a-large-working-scam-page
@ashanti-shatoshi Perhaps you can remove Cryptonator from your list?
Generally, it is preferable to use hardware wallets or wallets on your own computers instead of any kind of online wallets as @moonbeam already mentioned.
