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.
Yes i agree on that, there are more countries today who are legalizing cryptocurrency and if bitcoins will be starting to pump up again today then there is a huge chance that $20k dollar might be surpassed due to a huge demand of investors in the market.
