So, it s just like reality of being. If we check the story of money (i meant papers) it started with exchanging the goods. Then we made that exchange with valuable stuffs like salt, silver, gold etc. In the updated version of story , her and now, we are talking about a digitalized world. The meaning of money and money itself have changed. It looks, blockchain and crypto's are pregnant to many more new things for next years. And i think whatever in the future is that The Steem will be the coolest currency. And your post is informative as before ...Thank you @taskmaster4450
