Discussion: What is your preferred crypto-currency platform?

As a bit of a scrub, I'm curious to know how others organize their various currencies.

Do you have preferred converters for Steemit?
Do you have a preferred wallet? (Does anyone use Coinbase, Coinspot, Coinpot?)
Does anyone have any experience with crypto debit or Visa pay cards?
Have you had any bad experiences with any company/wallet/converter you've chosen?
