Crypto currency has a greater future no doubt and we have already seen it since the inseption of Bitcoin in 2009 ehen its value was below a dollar and now above $8,500 as at time of this post.
The future of cryptocurrency are still questionable to other people but for me there's no reason to be scared because cryptocurrency will rule our financial system in the future. Cryptocurrency will be more stronger every year until every person will adopt the system and enjoy the function of a blockchain technology. Bitcoin will still be the leader of all cryptocurrency for sure, believe it or not.
