But, at the same time, we should stop talking about investing in cryptos. If you're American and consider buying some euros for a trip to Europe, are you investing in euros?
One of the main problems of this ecosystem is the permanent feeling, propagated by medias and forums alike, that cryptos are just investment and trading tools, if not scammy get rich schemes. They are not. They are the bricks on which we can build a better banking/financial world, and get more freedom.
A good resolution for 2019: what about giving up on investing and start using instead?
