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.
It will probably hit $20k dollar again since the market price today is very low and that is the reason why we should keep on holding our coins today and wait for bitcoins to skyrocket again before the year ends.
