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.
I really do not think that anything that extraordinary is needed to reach that price again, yes the market is not giving indications it is going to reach that price right now, but I do not mind I'm thinking in the long term and not in the short term, so as long as you are willing to be patient and hold your coins then seeing that price is inevitable the only problem is that I think that a majority of the users in this forum are going to see those prices and they are not going to have any bitcoin to benefit from it since they will sell before that.
