It's is already obsolete.
Only 7 transactions at the same time, with insane fee's. Nobody is going to use that on the long term.
The only thing that BTC has going or itself is that it's the most well-known. It's far from technically superior altcoins.
The 7 transactions are just the current bottleneck and that’s OKAY. we need to ensure security over speed first. 2nd layer solutions like lightning network will exponentially increase transaction speed.
At the end of the day, bitcoin can easily take the tech of successful chains and incorporate within itself.
