I know less than zero about any of these digital currencies...My car radio was tuned to Bloomberg last week and some expert was advsing listeners to stay away from them, unless maybe by using Coinbase.... I didn't absorb much of the conversation at all,,, But tell me does buying Bitcoin or some such currency through CoinBase provide some level of security.... I just don't get it at all. Interested but lack understanding, which as an old timer may have passed me bye.
