No my friend ico coin will mever surpass btc. Bitcoin has a natural growth and we got it from mining and i dont think any ico coin out there will surpasses bitcoin. Bitcoin is king of crypto and will be always king. The pioneer of thia industry even if the bitcoin tech is obsolete but many people will think about bitcoin if they talked about cryptocurrencies.
I think natural growth is due to mass hysteria and hype. Most people approach the blockchain mainly because of the financial aspects. Only a very few percentage take a look at the technology behind it.
Bitcoin has thrived long enough because it projected financial value, but when it comes down to the basic blockchain advantages, the problems of bitcoin begin to surface.
So, a more refined research into how blockchain can transform the overall economy is what top tier influences are after and not just temporal financial prospects.
Case in point; when you hear of regulation and standardization, it's not just pertaining to bitcoin but blockchain and all of its products. However, when you hear of a
'BAN' it most likely has to do with cryptocurrencies of which bitcoin is the most referred to (like you said 'king of crypto') and ICOs only because of unregulated and anonymous crowdfunding source and destinations.
