About 3 years ago amid the rising number of altcoins and ICOs, some bitcoin maximalists wrote reasons of why those altcoins would ultimately fail, and bitcoin would eventually dominate. Some of these articles can be found on Nakamoto institute website. Very interesting read.
The prediction sounds ridiculous to some people, but now it seems to come true. Bitcoin rising in value, and altcoins slowly bleeding to non-existence.
One thing many people don't realise is: market cap / money flow / coin price aren't necessarily linked to superior technology. Money is a collected hallucination. You can have outdated technology which people want to put the money in, or superior technology which no one cares.
There is not really much to go on regarding BTC vs alts because in reality some of the alts are faster,cheaper and better than BTC.
Most of the ICO alts are almost dead , it really doe snot matter if the ICO behind them was legit or shit. Its all about speculation and drive to make money!
