The subject of crypto coins is a subject that's on the table. At present there are many crypto coins, but I have only heard about crypto coins such as Bitcoin and Dash that have similar characteristics, although in my country I have known that instant and private transactions have been made in some trading sites only with the latter. Before it was a topic that was silenced, but now most people know about coins and blockchain. So far it seems that having crypto currencies is a business, although, like any business, it carries its risks by the ups and downs that happen and influence the investments for good or for bad as the case may be. I think it will take some time for them to be accepted, but this will change the world. Thanks to Steemit we are familiar with SBD and Steem as fiat currencies. Thanks to @techblogger for the interesting publication and @adsactly for sharing it.
