Many reason pointed out in the article to believe in the future of Bitcoin :
https://www.cnbc.com/2018/05/26/bitcoin-still-a-buy-says-blockchain-venture-capitalist.htmlAlso a good statement about ethereum and its relation to ICOs:
"Bogart said he's especially cautious with ethereum, which he said has a lot of overhang because so many initial coin offerings (ICOs) have been built on top of ethereum. He pointed out that if the ICOs don't work out, that could be bad news for the platform its built on. "
It's all just opinions, so my is that it will hit 20k, and I am coming back to this post to say I was right lol.
Just think positive and believe that cryptocurrency will reach $20k dollars again by the end of this year, there are a lot of crypto analyst who are saying that bitcoins might even surpass $20k dollars because there are more countries that are being legalized by their government this year.
