I don't see any problems with the price of streem despite this graph https://coinmarketcap.com/currencies/steem/

For me cryptocurrency is cool, because they retains the positive elements of the gold standard (only a limited amount available, countries can’t just increase the amount of cryptocurrency to try and artificially stimulate the economy). 

Also, at the same time, the big ones like bitcoin are becoming more and more liquid. Then, think about how hard it is to steal – almost impossible unless more than half of bitcoin owners are in on it, I am led to believe. But with the new cryptocurrencies its probably impossible. 

And it is easy to “carry” – you don’t need to carry anything around except your passwords! As I said, I’m no expert in cryptocurrency, so please comment and correct me if I gave some incorrect facts. Also comment if you have some cool ideas to add! And upvote and follow me!!! LOL
