Earlier quoted context omitted.
That's a very simplistic way to look at it. Before the latest huge price increase, bitcoin had very little real competition. Now it has proved that its artificially crippled capacity of 1MB is an enormous problem and that the limited throughput couldn't even come close to handling the last bubble smoothly.
My comment is intended to speak to cryptocurrency as a whole (the OP topic) rather than Bitcoin specifically relative to other cryptocurrencies. I welcome links to charts that show, e.g., total crypto market cap on a log scale.
You said bitcoin twice and linked to btc's price over time, I'm not sure why anyone would take that to mean crypto-currencies in general.
This seems like a textbook example of moving goal posts.
