The best part: No fees! Thankfully, the app makes it easy to send your digital currency to another wallet. The biggest downside is that Robinhood only works in 16 states for cryptocurrency trades, but it plans to add more in the future. If so, the fee will be listed on the trade confirmation before you complete a transaction. The cryptocurrency markets have calmed down a bit since that record high, but many Bitcoin evangelists still claim Bitcoin to be the currency of the future.
